500 cal are added to 10 g of water (specific heat of 1.000 cal/g °C) originally at 20 °C. The final temperature is ________.

Question

Quizplus · Accepted Answer

The amount of heat (q) added to a substance can be calculated using the formula q = mcΔT, where m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Given 500 cal are added to 10 g of water with a specific heat of 1.000 cal/g°C, ΔT can be found by rearranging the formula to ΔT = q / (mc). Substituting the given values, ΔT = 500 cal / (10 g * 1.000 cal/g°C) = 50°C. Since the initial temperature is 20°C, the final temperature is 20°C + 50°C = 70°C.
