Final answer:

The mass of water that will change its temperature by 7.0°C when 1525 J of heat is added to it is approximately 0.052 kg or 52 grams.

Step-by-step explanation:

To determine the mass of water that will change its temperature by 7.0°C when 1525 J of heat is added to it, we need to use the formula:

q = mcΔT

where q is the heat added, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.

Rearranging the formula to solve for m:

m = q / (cΔT)

Plugging in the given values:

m = 1525 J / (4186 J/kg/°C x 7.0°C)

m ≈ 0.052 kg or 52 grams
