States of Matter/Heat Flow

What is evaporation?

• The process of liquid water turning into ice when cooled.

• The process by which liquid water turns into water vapor (gas) when it is heated.

• The process of water vapor condensing into liquid water.

• The process of water being absorbed by soil.

What is condensation?

• The process where a gas turns into a liquid when it cools down.

• The process of a liquid turning into a gas when heated.

• The process of solid turning into a liquid when heated.

• The process of a gas turning into a solid without becoming a liquid.

What is the dependent variable in an experiment?

• The factor that is manipulated by the researcher.

• The factor that is measured or observed in an experiment.

• The constant factor that remains unchanged throughout the experiment.

• The initial condition before any changes are made.

What is radiation?

• Radiation is the transfer of heat energy through electromagnetic waves.

• Radiation is the process of converting light into sound.

• Radiation is a type of energy that can only travel through solid materials.

• Radiation is the movement of particles in a vacuum.

What is sublimation?

• The process where a solid turns directly into a gas without passing through the liquid state.

• The process of a gas turning into a liquid.

• The process of a liquid turning into a solid.

• The process of a solid turning into a liquid.

What is freezing?

• Freezing is the process where a liquid turns into a solid when it loses heat.

• Freezing is the process where a solid turns into a liquid when it gains heat.

• Freezing is the process of heating a solid to make it melt.

• Freezing is the process of evaporating a liquid into gas.

What is the role of heat in changing states of matter?

• Heat energy is required to change the state of matter.

• Heat has no effect on the state of matter.

• Heat only changes the temperature, not the state.

• Heat can only change solids to liquids, not gases.

What is the principle of thermal expansion?

• Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.

• Thermal expansion refers to the increase in mass of a substance when heated.

• Thermal expansion is the process of a substance becoming denser when heated.

• Thermal expansion occurs only in gases and not in liquids or solids.

What is the difference between temperature and heat?

• Temperature is the total energy of all the molecules in a substance, while heat is the energy of motion of the molecules.

• Temperature is a measure of the average kinetic energy of the molecules in a substance, while heat is the energy transferred between substances due to a temperature difference.

• Temperature and heat are the same thing and can be used interchangeably.

• Temperature is a measure of how hot or cold something is, while heat is the energy stored in an object.

What is the process of melting?

• The process where a solid turns into a liquid when heat is applied.

• The process of freezing a liquid into a solid.

• The process of evaporating a liquid into a gas.

• The process of condensing a gas into a liquid.
