Answer to Problem 8E

The friend’s recommendation to bring clothing for warm weather in Hawaii where the forecast is for a temperature of 31⁰C to 28⁰C is good.

Explanation of Solution

The normal room temperature is approximately $25{}^{\text{o}}\text{C}$ . It is known that freezing point of water is $0{}^{\text{o}}\text{C}$ and boiling point is $100{}^{\text{o}}\text{C}$ . Thus, as temperature rises weather becomes hot and as temperature decreases weather becomes cold.

A temperature of 31⁰C to 28⁰C is above room temperature thus, it will be a warm weather and recommendation by friend to bring warm weather clothes is good.
