Question
- A kettle containing water at 30 °C is heated to 100°C. Find the change in temperature in: i) °C ii) K
Solution
i) The change in temperature in degrees Celsius (°C) is calculated by subtracting the initial temperature from the final temperature. So, 100°C (final temperature) - 30°C (initial temperature) = 70°C.
ii) The change in temperature in Kelvin (K) is the same as the change in degrees Celsius. This is because the size of the degree Celsius (°C) is the same as the size of the Kelvin (K), though their zero points are different. Therefore, the change in temperature is also 70K.
