• The amount of _______ in a substance affects the rate of energy transfer and how much energy is needed to increase the substance’s temperature.

• volume

• matter

• color

• mass

Answer explanation

The correct choice is 'matter' because the amount of matter in a substance directly impacts energy transfer and the energy required to change its temperature.

When light shines on something, it might reflect off particles, transmit between particles, or transfer energy into particles (absorption).

• Reflect, Transmit, Transfer

• Refract, Scatter, Diffuse

Answer explanation

The correct answer choices are Reflect, Transmit, Transfer. When light shines on something, it can either reflect off particles, transmit between particles, or transfer energy into particles through absorption.

Heat flows from:

• cold to hot

• hot to cold

• upwards

• left to right

Answer explanation

Heat flows from hot to cold due to the second law of thermodynamics, which states that heat naturally flows from higher temperature regions to lower temperature regions.

What happens to the speed of particles as the temperature increases?

• It decreases

• It remains the same

• It increases

Answer explanation

As the temperature increases, the speed of particles also increases due to the increase in kinetic energy, leading to faster movement.

Particles move the fastest in:

• Solid

• Liquid

• Gas

Answer explanation

Particles move the fastest in gas because the particles in a gas have the most kinetic energy and are free to move around rapidly.
