Question

A material was cooled from 100ºC to 40ºC. What is the temperature change?The specific heat of water is 4.18J/goC. I need the full explanation would mean a lot to me.

Answer 1

Answer:

-60°C

Explanation:

According to this question, a material was cooled from 100ºC to 40ºC.

The temperature change, which is symbolized by ∆T = final temperature - initial temperature

That is, ∆T = T2 - T1

In this question, T2 = 40°C, T1 = 100°C

Hence, ∆T = 40°C - 100°C

∆T = -60°C
