2A Kinetic Theory and Temperature

What results from evaporation according to the kinetic energy model?

• Cooling

• Heating

• Expansion

• Compression

What is the relationship between temperature and kinetic energy?

• Directly proportional

• Inversely proportional

• No relationship

• Exponentially related

Which temperature scale is commonly used for everyday temperature measurements?

• Kelvin

• Rankine

• Celsius

• Fahrenheit

What is the temperature of absolute zero in Kelvin?

• 0 K

• 273 K

• 100 K

• 373 K

Crocodiles are cold-blooded and typically maintain their internal temperatures at an average of approximately 30 °C. What temperature in Kelvin does this correspond to?

• 243 K

• 73 K

• 303 K

• 373 K

• I don’t know.

What does the kinetic theory of matter state about particles?

• Particles are stationary.

• Particles are in constant random motion.

• Particles are only in motion when heated.

• Particles do not move in solids.

What determines the temperature of a solid, liquid, or gas?

• The chemical composition

• The kinetic energy

• The potential energy

• The gravitational force

Identify the correct statement about two different gases, A and B. These gases have the same volume.

• If A is hotter than B, it will always contain a greater total energy.

• If A is cooler than B, it will always have a lower average translational kinetic energy.

• Both gases have the same number of particles.

• If both gases are at the same temperature, then the particles must have the same speed.

• I don’t know.

What happens when particles collide?

• Kinetic energy is passed between them

• They stop moving

• They lose all energy

• They gain potential energy

What is the approximate room temperature in Celsius?

• 27°C

• 0°C

• 100°C

• -273°C
