Final answer:

To determine the heat required to raise the temperature of 17 grams of water from 10°C to 25°C, use the formula q = mcΔT with water's specific heat capacity. The calculated heat energy needed is 1065.3 Joules.

Step-by-step explanation:

To calculate the heat required to change the temperature of 17 grams of water from 10°C to 25°C, you use the specific heat capacity formula: q = mcΔT, where q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Water's specific heat capacity is approximately 4.18 J/g°C. Plugging in the values, we get:

q = 17 g × 4.18 J/g°C × (25°C - 10°C)

ΔT is the temperature change, which is 25°C - 10°C = 15°C. So the calculation is:

q = 17 g × 4.18 J/g°C × 15°C = 1065.3 J

So, the heat required to raise the temperature of 17 grams of water from 10°C to 25°C is 1065.3 Joules.
