Answer 1

Answer:

q4: that's the max temperature of our body

q26: it will be transferred from the bigger object to smaller object as the bigger object has more heat than the smaller one

Answer 2

1.thermal conductivity

2.radiation

3. Conduction is a type of heat transfer that can only happen in gas or liquid because convection happen when there is difference in temperature between two part of liquid or gas .

4. Clinical thermometer have marking below 42 degree Celsius because it is made to use human temperature inhuman temperature never exceed from 42 degree Celsius

25. Because black is a dark colour and dark colour absorb more heat.

hope this may help you
