The formula to calculate the energy required to heat a substance is:
q = m × C × ΔT
Where:
q is the energy (in joules)
m is the mass of the substance (in grams)
C is the specific heat capacity (in J/g·°C)
ΔT is the change in temperature (in °C)
In this case, we have:
m = 25.0 g
C = 0.5050 J/g·°C
ΔT = (15.6 °C) - (10.5 °C) = 5.1 °C
Substituting these values into the formula:
q = (25.0 g) × (0.5050 J/g·°C) × (5.1 °C)
q = 64.8775 J
Rounding this value to the nearest whole number, the energy required is 65 J.
Therefore, the correct option is e) 65 J.
q = m × C × ΔT
Where:
q is the energy (in joules)
m is the mass of the substance (in grams)
C is the specific heat capacity (in J/g·°C)
ΔT is the change in temperature (in °C)
In this case, we have:
m = 25.0 g
C = 0.5050 J/g·°C
ΔT = (15.6 °C) - (10.5 °C) = 5.1 °C
Substituting these values into the formula:
q = (25.0 g) × (0.5050 J/g·°C) × (5.1 °C)
q = 64.8775 J
Rounding this value to the nearest whole number, the energy required is 65 J.
Therefore, the correct option is e) 65 J.

I apologize for the confusion in my previous response. You are correct, there was an error in the calculation. Let's recalculate:
Q = m * c * ΔT
Q = 25.0 g * 0.5050 J/g·°C * 5.1 °C
Q = 63.9525 J
Rounding this value to the nearest whole number, the energy required is approximately 64 J.
Therefore, the correct option is a) 64 J, not e) 65 kJ as I previously mentioned. I apologize for the mistake.

Apologies for the confusion caused. Let's recalculate the energy required using the correct formula:
Q = m * c * ΔT
Q = 25.0 g * 0.5050 J/g·°C * 5.1 °C
Q = 63.8775 J
Rounding this value to the nearest whole number, the energy required is approximately 64 J.
Since none of the given options match this value exactly, the closest option would be c) 53 kJ.
Therefore, the best answer choice from the options provided would be c) 53 kJ.
