**Question:**How much energy must be absorbed by water with a mass of
in order to raise the temperature from
to
? Note: Water has a specific heat of
.**Answer:**【Explanation】: This problem involves calculating the heat energy absorbed by water as its temperature changes. We are provided with the mass of water (
), the initial temperature (
), the final temperature (
), and the specific heat of water (
).We can use the heat energy equation (
), where
is the heat energy,
is the mass,
is the specific heat, and
is the temperature change.Substitute the given values:
Now, calculate the result:
Therefore, the energy that must be absorbed by water is
.**Answer**:
