"If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases when pressure is held constant. How does heat move during the process of convection? When two objects of different temperatures are placed in contact with each other, heat will flow from the hotter object to the cooler object until both objects reach the same temperature. How did you use the result to determine who walked fastest and slowest? Simply due to geometry, at high temperatures, molecules will tend to be far apart. Also in general, for any substance, when temperature increases, the total energy (includes kinetic and vibrational) increases, as temperature is a measure of energy of a system. So when an ice cube is exposed to heat, its water molecules absorb heat energy from the surrounding atmosphere and begin to move more energetically, causing the water ice to melt into liquid water. Connect and share knowledge within a single location that is structured and easy to search. Explanation: When we decrease the temperature, less heat energy is supplied to the atoms, and so their average kinetic energy decreases.
