What happens when energy is taken away from matter?
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
What happens to the mass of a substance as the temperature is increased?
The temperature of a substance has no effect on its mass.UNLESS ... part of it evaporates and blows away, or melts in a puddle and runs off the edge of the table.As long as all of the substance stays there, its mass doesn't change, no matter how hot or cold it gets.
What happens to the particles of matter when thermal energy is taken away from it?
When thermal energy is taken away from matter, the particles will lose energy and slow down, leading to a decrease in temperature. As the particles slow down, they may eventually come together and form a solid if enough energy is removed. This process is known as cooling or condensation.
What happens if the energy of a photon exceeds that necessary for pair production?
If the energy of a photon exceeds the threshold energy for pair production, the excess energy will be carried away by the produced particles as kinetic energy. This additional energy will contribute to the speed at which the particles are created and will increase their momentum.
Why are particles always in motion?
Particles are always in motion because they have an amount of heat energy stored within them. As additional heat is added, the substance's particles gain more energy, and will in turn increase distance between themselves, and weaken the bonds between them. In turn, when heat is taken away from a substance (it is cooled down) the particles loose energy, and the distance between them will decrease, causing the bonds between them to strengthen. The whole idea is known as the particle theory. However, particles may not be always in motion. Scientists discovered the temperature point of absolute zero, which is -273.15°C, or 0°K (Kelvin). This is the lowest temperature possible.
What happens is energy is taken away from matter?
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.

What happens to particles of a substance as it is heated?
When particles are heated they get very energetic and try to break away from their bonds to eachother. At the start they make tiny vibrations and gradually get very fast and can turn into a liquad.
What happens to volume when the substance is heated?
When you heat something (gas, liquid, solid) it's volume increases. Sometimes it is not a visible change, yet volume increases by small amount. That is because by applying heat you make participles that are building the substacne dirft away from each other.
What happens when you take the heat away from a substance?
Physical change
What happens when heat is added to a substance?
well this isn't a specific question you see there is 2 different kind of substances ; For example:... solid : when heat is added to a solid it becomes a liquid liquid: when heat is added to a liquid it becomes a gas! for example water > if you add heat it will hot add or take away chemicals!
What happens to energy as it travels away from the sources?
Energy is lost
What happens molecularly when a substance goes through a phases to get from a solid to a gas?
The particle theory states that all particles are made of matter, these particles are in constant motion and there is a force of attraction between these particles. Solids have more closely packed particles and thse particles get looser as they progress through the states from liquid to gas. Therefore, moleculary, the molecules move faster and faster and appear farther and farther away from each other.
