What happens to substances as they lose or gain energy?
expand or contract
What conversion do water molecules lose speed?
When water goes from a gas to a liquid, or a liquid to a solid, the water molecules have lower kinetic energy, and therefore they lose speed.
What happens to the molecules in a substance when thermal energy is removed?
It's vibrates and then melts
What happens to water molecules as water evaporates?
The hydrogen bonds between the water molecules in the liquid are broken.
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
This energy is released as a photon.
What happens to molecules as energy is added and the temperature increases?
what happens to molecules as energy is added the temperature increses
In terms of energywhat happens to water in a freezer?
water molecules lose energy to their surroundings, causing the molecules to move less, thus the liquid water becomes a solid
What happens when matter cools?
One thing that happens is that the molecules in the matter lose energy and momentum and slow down, therefore the matter becomes more compact.
What happens to the potential energy of the molecules in a?
The potential energy of the molecules change during a reaction.
What happens as electronics move along the chain of molecules known as the electron transport chain?
They lose energy,which is then used by the cell to make ATP
What happens to a sample of matter when its particles lose kinetic energy?
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
What happens when liquid solids or gas absorb heat?
the molecules gain or lose energy, the more energy these molecules have the easy it is for them to break the bonds holding them together, thus when you apply enough heat to a substance it changes from a solid to a liquid then from a liquid to a gas.
What happens to energy as it passes through many molecules?
nothing happens
What happens to molecules as their potential energy increase?
will be transformed into kinetic energy
What happens when you put ice cream in the refrigerator what happens to the molecules and the energy?
the molecules freeze and it turns to the freezing point
What best describes what happens to energy and molecules in a stable ecosystem?
Energy is continuously added to the ecosystem and molecules are recycled.
What happens when organic molecules decompose?
energy is released
