Question

4. What happens on PE days and why?​

Answer 1

Answer:

The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively.

Answer 2

Explanation:

Physical activity also promotes healthy body weight, which reduces the number of school days a child misses due to illness, further supporting their learning. In other words, taking time out of the school day for physical activity doesn't detract from academic performance – it helps support it.
