10 Questions
What happens when a substance is cooled?
The atoms/molecules lose energy and move slower.
What does temperature measure?
The average speed of atoms/molecules
How does heating a substance affect the volume?
The volume of the substance increases as atoms/molecules spread further apart.
What happens to the temperature of a substance when its particles are moving slower?
The temperature is lower
How are collisions affected when a substance is cooled?
Collisions become weaker and less frequent
Which statement accurately describes the relationship between the speed of particles and temperature?
The faster the particles move, the higher the temperature.
When a substance is heated, what happens to the volume of the substance?
The volume increases due to the particles moving further apart.
What is the primary reason for the change in volume when a substance is heated or cooled?
The change in the frequency and strength of collisions between atoms/molecules.
If a substance is cooled, what happens to the strength and frequency of collisions between its atoms/molecules?
The collisions become weaker and less frequent.
What is the primary mechanism by which energy is transferred to or from a substance during heating or cooling?
The change in the speed of atoms/molecules within the substance.
Test your knowledge on the concepts of heating and cooling substances, energy transfer, temperature changes, and the speed of atoms and molecules. Understand the relationship between energy transfer and changes in temperature.
