What is temperature a measurement of?

The average kinetic energy of a system.

The amount of heat.

The amount of cold particles in the system.

The change in temperature at equilibrium.

Why should you wait for temperature to stabilize before taking a reading?

Energy is transferring from the warm system to the cooler 1

It takes time for the colder particles to transfer

Kinetic energy is apt to change on a whim.

Because temperature should always be taken after 5 minutes.

What are the best units for measuring temperature in a physical science lab?

Kelvin and Celsius.

Fahrenheit and Celsius.

Calories and Kilojoules.

Joules or Fahrenheit.

What is kinetic energy?

Energy in motion.

The average energy of a system.

Potential energy

Heat energy.

When measuring temperature, why should you keep your thermometer suspended in the system?

All of the answers are correct.

To ensure only the temperature of the system is taken.

To decrease the chances of breaking the therm or the contain

To avoid taking the temperature of the container.
