How many Joules of heat are required to raise the temperature of 35 mL of water from 25 °C to 100 °C?

Question

Quizplus · Accepted Answer

The formula to calculate heat (q) is:
q = m * c * ΔT
where
m = mass of the substance (in grams or mL)
c = specific heat of the substance (for water, it is 4.18 J/g°C or 4.18 J/mL°C)
ΔT = change in temperature (in °C or K)

Here, m = 35 mL, c = 4.18 J/mL°C, ΔT = 100 - 25 = 75°C

Putting the values in the formula, we get:
q = 35 * 4.18 * 75
q = 1.1 × 10^4 J

Therefore, the answer is C) 1.1 × 10^4 J.
