What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees Celsius to 30.0 degrees Celsius? Specific heat capacity of silver is 236 J/(kg * C°)

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

Best regards.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
