Question

1)

What does a steeper line on the temperature against energy graph mean?

A new liquid is added to the experiment and measured to have a greater specific heat than water. How would the graph of temperature against energy look for this liquid?

Cold water has a substantially larger specific heat than warm water.

If you add equal amounts of heat to equal masses of water and alcohol, which will stay closest to its initial temperature?

Thicker liquids have higher specific heats.

What does a steeper line on the temperature against energy graph mean?

Greater specific heat Lesser specific heat Can't tell without knowing mass Unrelated to specific heat

Explanation / Answer

1) q = m Cp(Tf-T0)

So we cannot tell the without knowing the mass of the substance.

The correct option is C.

2) Steeper than for water(option A is correct)

3) False.

4) none of the above, since we cannot say the initial temperature unless the final temperature is known.
