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.

-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

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
