In most cases, which expands more for comparable changes in temperature?
gases
The moderate temperatures of islands throughout the world has much to do with water's
high specific heat capacity
Compared to a giant iceberg, a hot cup of coffee has

The quantity of heat that a substance can transfer relates to its
Change in temperature
If the temperature of a sample of water at 0°C is slightly increased, the volume of the water
Decreases
It is important that the two metals that make up a bimetallic strip have
Different rates of expansion
A substance that cools down faster than others has a
High specific heat capacity
Aluminum has a higher specific heat capacity than iron. This means that for equal masses of aluminum and iron, the metal that heats more quickly when the same amount of heat is applied is
Iron
A temperature difference of 20° Celsius is also equal to the temperature difference of 20 on the
Kelvin scale
