Final answer:

To find the heat required to raise the temperature of a 32 g sample of water from 8 °C to 22 °C, you use the formula q = mcΔT, resulting in 1869.408 J. It appears there is an error as this correct calculation does not match any provided answer choice.

Step-by-step explanation:

To calculate the amount of heat required to raise the temperature of a 32 g sample of water from 8 °C to 22 °C, we use the formula: q = mcΔT, where:

  • q is the heat energy (in joules),
  • m is the mass of the water (in grams),
  • c is the specific heat capacity of water (4.184 J/g°C), and
  • ΔT is the change in temperature (in °C).

Plugging the values into the equation, we get:

q = (32 g) × (4.184 J/g°C) × (22 °C - 8 °C)

q = (32 g) × (4.184 J/g°C) × (14 °C)

q = (32 g) × (4.184 J/g°C) × (14)

q = 1869.408 J

However, since this result does not match any of the options given, there might be a mistake in the question or provided options.
