Answers are for parents and teachers.
1
Convert 37 °C to kelvin and °F.
37 + 273 = 310 K; 1.8 × 37 + 32 = 98.6 °F.
2
A temperature rises by 10 K. By how many °C does it rise?
By 10 °C, because a change of 1 K equals a change of 1 °C.
3
Change 800 N/m² into mbar.
800 ÷ 100 = 8 mbar.
4
Name one example each of conduction, convection and radiation from daily life.
For example: a spoon in hot tea (conduction); warm air rising from a heater (convection); sunshine on the skin (radiation).
