Level 1Temperature and Kinetic Energy

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

How does mass affect the speed of particles at the same temperature?

Back

Less massive particles move faster than more massive particles at the same temperature.

Front

What happens to the kinetic energy of particles when temperature increases?

Back

The kinetic energy of particles increases, causing them to move further apart.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

Higher temperature means higher kinetic energy in gas particles.

Front

What can be inferred if particles in one sample are moving faster than those in another sample at the same substance?

Back

The sample with faster-moving particles has a higher temperature.

Front

What effect does temperature have on the movement of particles in a solid?

Back

An increase in temperature causes particles in a solid to vibrate more and move further apart.

Front

What is the effect of mass on the kinetic energy of particles?

Back

Lighter particles require less energy to move fast compared to heavier particles.

Front

What happens to the speed of particles when they are heated?

Back

When particles are heated, they gain kinetic energy and move faster.

Front

What is the definition of a gas?

Back

A gas is a state of matter where particles are far apart and move freely.
