Question

A glass of cold water has a temperature of 42.0°E What is this in units of K?

Answer 1

42°C is equivalent to 315.15 K.

Step-by-step explanation:

In this question, we need to convert the temperature from one scale to another. A glass of cold water has a temperature of 42 °C. The conversion from degree Celsius to kelvin is given by :

`T_k=T_c+273.15`

Where

`T_c\ and\ T_k` are temperatures in degree Celsius and kelvin respectively.

So,
`T_k=42+273.15`

`T_k=315.15\ K`

So, 42°C is equivalent to 315.15 K. Hence, this is the required solution.
