The specific heat capacity of liquid water is 4.18 J/g-K. How many joules of heat are needed to raise the temperature of 5.00 g of water from 25.1 °C to 65.3 °C?

Question

Quizplus · Accepted Answer

Using the formula Q = m * c * deltaT where Q is the heat energy, m is the mass, c is the specific heat capacity, and deltaT is the change in temperature, we get:
Q = 5.00 g * 4.18 J/(g*K) * (65.3 °C - 25.1 °C) = 840 J. Therefore, the answer is B.

The Specific Heat Capacity of Liquid Water Is 4
