Eventually, they have enough energy to overcome the attractions that hold them together and they begin to move independently of one another.  When this happens, the water is said to be boiling.\n\n <br><br>The boiling point is the temperature at which the molecules have enough energy to overcome the attractions that hold them together.  The attractions are the intermolecular forces, which are the attractive forces between molecules.  The stronger the intermolecular forces, the higher the boiling point.\n\n <br><br>Water has strong intermolecular forces because of the way the molecules are arranged.  The oxygen atom has a partial negative charge and the hydrogen atoms have partial positive charges.  The charges attract each other, and the water molecules are held together.\n\n <br><br>The boiling point of water is 100 degrees Celsius (212 degrees Fahrenheit).  At this temperature, the water molecules have enough energy to overcome the attractions that hold them together.  <\/p>\n            \n            <h2>PHYSICS\/CHEMISTRY &#8211; Heat energy, melting, boiling process<\/h2>\n            \n    <figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n    <iframe loading=\"lazy\" title=\"PHYSICS\/CHEMISTRY - Heat energy, melting, boiling process\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/bBORofHG9sU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n    <\/div><\/figure>\n            <p>When water reaches its boiling point, the molecules have enough energy to break free from the water&#8217;s surface and become vapor.  The vapor then rises into the air, leaving the water behind.\n\n The reason energy is required for this process is because water molecules are held together by hydrogen bonds.  <br><br>In order for the molecules to break free from the surface of the water, they need to absorb energy to break those bonds.  Once the bonds are broken, the molecules can rise into the air and escape the liquid state.\n\n So, in short, energy is required to break the hydrogen bonds that hold water molecules together.  <br><br>Once those bonds are broken, the molecules can escape the liquid state and turn into vapor. <\/p>\n            \n            <h2>When water at 0\u00b0c freezes, is heat lost or gained? explain your answer.<\/h2>\n            \n            <p>When water freezes at 0\u00b0c, it undergoes a change of state from liquid to solid.  This change of state is accompanied by the release of latent heat, which results in a loss of heat for the water.  The water becomes colder as it loses heat to the surrounding environment. <\/p>\n            \n            <h2>Why is energy required for the boiling process quizlet<\/h2>\n            \n            <p>When water is heated, the molecules begin to move faster.  Eventually, they move so fast that they break free of the attractions that hold them together in liquid form.  When this happens, the water vaporizes, or changes to a gas.\n\n <br><br>The reason energy is required for this process is because it takes a lot of energy to overcome the attractions between the water molecules.  In other words, it takes a lot of energy to get the molecules moving fast enough to break free from each other.\n\n The amount of energy required to vaporize a given amount of water depends on the temperature of the water.  <br><br>The higher the temperature, the less energy is required.  This is why it takes less energy to boil water at sea level than it does at high altitudes. <\/p>\n            \n            <h2>The amount of energy required to boil a substance<\/h2>\n            \n            <p>The amount of energy required to boil a substance is known as the latent heat of vaporization.  The latent heat of vaporization is the amount of heat required to change the state of a substance from a liquid to a gas.  The latent heat of vaporization is a measure of the energy required to break the bonds between the molecules of a substance.  <br><br>The latent heat of vaporization is typically expressed in terms of joules per mole (J\/mol).  The latent heat of vaporization is a measure of the entropy of vaporization.  The entropy of vaporization is the change in entropy when a substance changes from a liquid to a gas.  <br><br>The entropy of vaporization is a measure of the disorder of a substance.  The latent heat of vaporization is a measure of the energy required to overcome the intermolecular forces of a substance.  The latent heat of vaporization is typically expressed in terms of joules per mole (J\/mol). <\/p>\n            \n            <h2>How many joules are required for each of the following changes<\/h2>\n            \n            <p>Joules are a unit of measurement for energy.  One joule is equal to the amount of energy required to produce one watt of power for one second.  In order to determine how many joules are required for a given change, we must first determine the power (in watts) and the time (in seconds) required for the change.\n\n <br><br>For example, let&#8217;s say we want to know how many joules are required to raise the temperature of one kilogram of water by one degree Celsius.  We know that it takes 4186 joules of energy to raise the temperature of one kilogram of water by one degree Celsius.  Therefore, it would take 4186 joules of energy to raise the temperature of one kilogram of water by one degree Celsius.\n\n <br><br>Now let&#8217;s look at some other examples:\n\n 1. How many joules are required to raise the temperature of one kilogram of water by one degree Celsius?\n\n <\/p>\n            \n            <h2>How many joules are required to melt 12.8 g of ice at 0\u00b0c<\/h2>\n            \n            <p>In order to melt 12.8 g of ice at 0\u00b0c, 54.4 joules of energy are required.  This is because it takes 79.2 joules of energy to heat up the ice to 0\u00b0c (the melting point of ice), and then the ice will absorb 79.2 joules of energy in order to melt. <\/p>\n            \n                                            <p><\/p>\n                                             \n            <h2>Why is energy needed to boil water?<\/h2>\n            \n            <p>When water is heated, the molecules begin to move faster.
