Water is used in car radiators because :
- it is a good conductor of heat.
- it conducts heat faster as compared to the other substances and cools the engine quickly.
- its specific heat capacity is very low.
- its specific heat capacity is very high so it can cool the engine without a greater increase in its own temperature.
The heaviest nuclear radiation is :
- x-radiation
- α-radiation
- γ-radiation
- β−radiation
