Heat: Temperature, Thermometers and Transfer

Heat and Temperature Tools

Question 1mcq

Which statement best distinguishes heat from temperature?

A.Heat is energy that flows due to temperature difference; temperature tells how hot or cold something is.

B.Heat and temperature are exactly the same quantity.

C.Temperature flows from one body to another.

D.Heat is measured only by colour, not instruments.

Question 2mcq

Two cups have the same temperature, but one cup has more water. Which statement is most reasonable?

A.The larger cup must have a higher temperature.

B.Both are equally hot, but the larger cup may contain more heat energy.

C.The smaller cup must contain more heat because it cools faster.

D.Same temperature means same amount of matter and heat.

Question 3mcq

What is a clinical thermometer mainly used to measure?

A.Temperature of boiling oil

B.Room length

C.Human body temperature

D.Mass of a metal rod

Question 4mcq

Why is a laboratory thermometer not ideal for measuring body temperature at home?

A.It measures only mass.

B.It cannot measure temperature at all.

C.It always reads exactly

100^\circ C

D.It may not have the special design/range needed for safe body-temperature measurement.

Question 5mcq

A student removes a laboratory thermometer from hot water and then reads it after a delay. What is likely wrong?

A.The reading may change after removal, so it should be read while the bulb is still in the liquid.

B.The thermometer will show mass instead.

C.The reading becomes more accurate after a long delay.

D.The bulb should never touch any liquid.

How Heat Moves

Question 6mcq

Heat transfer through a metal spoon placed in hot tea is mainly due to?

A.Evaporation only

B.Conduction

C.Photosynthesis

D.Magnetism

Question 7mcq

Warm water rising and cool water sinking in a beaker is an example of?

A.Conduction only

B.Radiation only

C.Convection

D.Condensation

Question 8mcq

How does heat from the Sun reach Earth through space?

A.Conduction through metal rods

B.Convection through water currents

C.Scouring

D.Radiation

Question 9mcq

Which material is a good conductor of heat?

A.Copper

B.Wood

C.Plastic

D.Wool

Question 10mcq

Why are cooking pan handles often made of plastic or wood?

A.They conduct heat faster than metal.

B.They are poor conductors, so the handle does not heat up quickly.

C.They turn heat into light.

D.They make food cook without a flame.
