Nuclear fusion within the sun takes place within the
1 answer:
Answer:
Within the core
Explanation:
The core of the sun (and of every star) is the central part of the star, the hottest one.
Its temperature is about 10 million Kelvin degrees and more - and this temperature is enough to allow the nuclei of hydrogen to overcome the electrostatic repulsion between each other and come close enough to initiate the nuclear fusion.
The nuclear fusion is the process that produces energy in a star: in a nuclear fusion reaction, the nuclei of hydrogen fuse together to form nuclei of helium, and since the mass of the final products is less than the mass of the initial products, part of the mass is converted into energy, according to Einstein's famous equation

Answer:
Q = 836.4 Joules.
Explanation:
Given the following data;
Mass = 100 grams
Initial temperature = 25°C
Final temperature = 45°C
We know that the specific heat capacity of water is equal to 4.182 J/g°C.
To find the quantity of heat;
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.
dt = T2 - T1
dt = 45 - 25
dt = 20°C
Substituting the values into the equation, we have;
Q = 836.4 Joules.
