What substance easily travel across the cell membrane glucose molecules water molecules or sodium?
Of the three, water will move easily. The others require help and therefore the use of energy.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
What is the measurement of the average kinetic energy of the molecules of a substance?
temperature is the average kinetic energy of a particle
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
IS Thermal energy is kinetic energy or potential energy?
Thermal energy in a substance is kinetic energy of the molecules that make up the substance.
Describe the motion of molecules of a substance change as the energy is increased?
As energy increases molecules begin to move faster and shake more vigorously if you take energy out molecules do the opposite.
How do energy and changes in energy change the state of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
How heat energy can change the states of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.

The type of energy that depends on how fast the molecules in a substance are moving?
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
For any given substance which state has the most thermal energy?
gas because the molecules are further apart and can move more easily.
How does the pressure and temperature of each air mass change?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
Type of energy that depends on how fast the molecules in a substance are moving?
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
What is the measurement of the average kinetic energy of the molecules of a substance?
temperature is the average kinetic energy of a particle
How is the thermal energy of a substance related to its state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.
