What has more thermal energy?
A substance’s total thermal energy depends on its temperature, number of atoms, and physical state. More atoms and higher temperature mean more thermal energy. If all other conditions are the same, substances in gas form have the most thermal energy, followed by liquids, then solids.
What happens to energy when you mix hot and cold water?
The kinetic energy of the particles in the hot water and the kinetic energy of the particles in the cold water changed when the two samples were mixed. The hot-water particles lost kinetic energy when they were mixed with the cold-water particles.
When you combine hot and cold water How is thermal energy transferred?
When the two systems are in contact, heat will be transferred through molecular collisions from the hotter system to the cooler system. The thermal energy will flow in that direction until the two objects are at the same temperature.
What process happen when you add hot water to cold?
When you add ice to hot water, some of the water’s heat melts the ice. The remaining heat warms the ice-cold water but cools the hot water in the process. You can calculate the mixture’s final temperature if you know how much hot water you started with, along with its temperature and how much ice you added.
Does thermal energy go from hot to cold or cold to hot?
And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.
Why does a hot cup of water have more thermal energy than cold water?
A rise in the temperature of matter makes the particles vibrate faster. Thermal energy is what we call energy that comes from the temperature of matter. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.
Does cold water have more thermal energy than hot water?
Increasing the temperature of something makes these molecules and atoms move around more quickly, giving it more thermal energy. Hot water has more thermal energy than cold water. Colder objects’ molecules and atoms move more slowly and have less thermal energy than warmer objects.

When you add ice to hot water, the ice melts and the hot water cools. This is based on the exchange of heat energy from the hot water to the ice. The exchange of energy causes the ice to melt. Once this happens, the cold water that was once ice will rise in temperature if it receives more energy from the hot water. …
Will a larger or smaller body of water lose heat faster?
If we assume that the two bodies of water have minimal surface area (Which can be proven to be a sphere) then the larger body of water has a greater surface area, and thus will lose heat faster. Note that ‘cooling’ and ‘losing heat’ aren’t synonymous. Your larger body of water, simply due to the fact that there’s more of it, has more heat energy.
