Answer:
the conversion of matter into energy
Explanation:
A nuclear reaction is a reaction in which there is a change in the nuclei of the atoms involved. The two most important examples of nuclear reactions are:
- Nuclear fission: it occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei
- Nuclear fusion: it occurs when two lighter nuclei fuse together into a heavier nucleus
In both cases, the total mass of the final products is smaller than the total mass of the initial nuclei: this means that part of the mass of the initial nuclei has been converted into energy, according to Einstein's formula:
where is the variation of mass and c is the speed of light. Since the value of c is very large, we can see from the formula that even a small amount of
is able to produce a huge amount of energy, and this is a typical feature of any nuclear reaction.
Answer:
Q = 266 Joules
Explanation:
Given the following data;
Mass = 20g
Initial temperature = 10°C
Final temperature = 29°C
Specific heat capacity of granite = 0.1 Cal/g°C to J/g°C = 0.7J/g°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
Substituting into the equation, we have;
Q = 20*0.7*(29-10)
Q = 14 * 19
Q = 266 Joules
