Question 5 of 10intermediate🔧 ApplyNumerical2 marks

A laboratory thermometer has 50 divisions between 0 °C and 100 °C. What does each division of this thermometer measure?

Correct Answer

The chapter explains in Activity 7.4 how to calculate the smallest value a thermometer can measure. The method is to divide the temperature range by the number of divisions.

In this case, the temperature range between 0 °C and 100 °C is 100 °C (100 - 0 = 100). With 50 divisions between these marks, each division represents 100 °C ÷ 50 = 2 °C.

Each division of this thermometer measures 2 °C.

Explanation

The chapter explains in Activity 7.4 how to calculate the smallest value a thermometer can measure. The method is to divide the temperature range by the number of divisions. In this case, the temperature range between 0 °C and 100 °C is 100 °C (100 - 0 = 100). With 50 divisions between these marks, each division represents 100 °C ÷ 50 = 2 °C.

Solution Steps

  1. Step 1: Identify the temperature range = 100 °C - 0 °C = 100 °C

  2. Step 2: Count the number of divisions between 0 °C and 100 °C = 50 divisions

  3. Step 3: Calculate the value of each division = Temperature range ÷ Number of divisions

  4. Step 4: Value of each division = 100 °C ÷ 50 = 2 °C
