Transfer of Heat and Its Effect (Part 1)

What is 'heat'?

• a type of feeling

• a type of energy

• a type of vibe

• a type of power

What is 'temperature'?

• a measure of how hot or cold something is

• a measure of how noisy or peaceful something is

• a measure of how dark or light something is

• a measure of how posh or tacky something is

What is the S.I. Unit of temperature?

• Degree

• Degree Celsius (⁰C)

• Kelvin (K)

• Degree Fahrenheit (⁰F)

Heat flows from . . .

• a region of low temperature to high temperature

• a region of no temperature to low temperature

• a region of high temperature to no temperature

• a region of high temperature to low temperature

As per the Kinetic Particle Theory, what happens to the particles in a solid when heated?

• particles lose energy and stop moving

• particles shrink in size and become denser

• particles gain energy and vibrate more rapidly

• particles change state from solid to liquid

As per the Kinetic Particle Theory, what happens to the particles in a liquid when heated?

• particles remain stationary

• particles gain energy, move faster and further apart

• particles transform into a gas state

• particles lose energy and move slower

The phenomenon of particles gaining energy and moving away from each other upon heating is called . . .

• thermal expansion
• heat expansion
• thermal contraction
• particle dispersion

Upon heating, the size of an object

• remains the same
• decreases

• increases

Does the mass of the object change when it undergoes thermal expansion?

• no

• only sometimes

• yes

Does the volume of the object change when it undergoes thermal expansion?

• no

• sometimes

• yes
