Explanation:
Heat
gained or loss in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC(T2-T1)
When two objects are in contact,
it should be that the heat lost is equal to what is gained by the other. So, the heat released by the lead is equal to the heat that is absorbed by the water.
</span>Heat = mC(T2-T1) = 50.0 mL (1.00 g/mL) (4.18 J/g °C) (20 °C - 18 °C) = 418 J<span>
</span>
Answer:
Because the distance is too far to count with any other way
Explanation:
Your right with chemical energy is stored in a piece of wood before its burned and then that it releases thermal energy whilst its being burned. It will also release sound energy but not nearly as much as thermal energy.
