Answer:
The heat energy stored within them changes
Explanation:
Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.
In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.
To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below
An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material
Answer : The mass of the water in two significant figures is, 
Explanation :
In this case the heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron metal = 
= specific heat of water = 
= mass of iron metal = 32.3 g
= mass of water = ?
= final temperature of mixture = 
= initial temperature of iron metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
Therefore, the mass of the water in two significant figures is,
Because pure silicon is a perfect semiconductor.
For room temperature, it rarely conducts, you can search for the threshold temperature, the characteristic equation is fairly complicated.
