20. Heat and Temperature

When equal amounts of heat are applied to equal masses of iron and silver, which metal warms up faster, and which one has the lower specific heat capacity ($c$)?

You are given a sample of an unknown metal. You weigh the sample and find that its weight is 29.4N. You add 1.25×10⁴ J of heat energy to the sample and find that its temperature increases from 52°C to 70°C. What is the specific heat of this unknown metal?

When equal amounts of $Q$ (heat) are applied to equal masses $m$, which substance warms up fastest: water, copper, sand, or ethanol?

Which of the following phenomena can be attributed to water's high $c$ (specific heat capacity)?

How does the $c$ (specific heat capacity) of water affect the climates of coastal regions?

Which of the following substances normally warms up faster when the same amount of heat is applied to equal masses?$\text{Q}=mc\Delta T$

When a thin metal wire is heated, how does its temperature change compare to that of a thicker wire made of the same material and heated with the same amount of energy ($Q$)?

Which statement correctly describes the specific heat capacity of water, given as $4.18 J/g °C$?

Which observation from the experiment best demonstrates that ice has a high $c$ (specific heat capacity)?
