How many joules of heat are required to raise the temperature of 20.0 grams of water from 30.0°C to 40.0°C?A 42 JB 84 JC 420 JD 840 J
Question
Solution 1
To solve this problem, we need to use the formula for heat transfer:
Q = mcΔT
where: Q = heat energy (Joules) m = mass (grams) c = specific heat capacity (Joules/gram °C) ΔT = change in temperature (°C)
For water, the specific heat capacity (c) is 4.18 J/g°C.
Given: m = 20.0 g ΔT = 40.0°C - 30.0 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
