Answer 1

The temperature was 3 degrees colder in the afternoon.

Explanations:

Given the following temperature values

• Temperature of thermometer in the morning = -2°C.

,

• Temperature of thermometer in the evening = -5°C.

Find the change in temperature

`\begin{gathered} \triangle t=-5^0C-(-2^0C) \\ \triangle t=-5^0C+2^0C \\ \triangle t=-3^0C \end{gathered}`

Note that the lower the temperature, the colder it will be and the higher the temperature, the warmer.

Since the temperature in the afternoon is lower than the temperature in the morning, hence the temperature is colder in the afternoon.

Based on the explanations above we can conclude that the temperature was 3 degrees colder in the afternoon.
