Respuesta :
temperature is where there are a difference of heat and cold, while energy is the main core
Answer : Energy impact the temperature of different substances differently because they have different heat capacity values.
Explanation :
Heat capacity is a quantity which gives us an idea about the amount of energy needed to raise the temperature of a substance by 1 degree.
Higher the heat capacity value, more energy is needed to raise the temperature. That means a substance which has higher heat capacity will heat slowly.
Let us understand this using an example.
Heat capacity of water is 4.184 J/gC and that of copper is 0.386 J/gC
Let us say we have 10 grams of each substance at 25 C.
We supply 100 J of energy to each of the above substance.
The amount of energy is calculated using the formula,
[tex] Q = m \times C \times \bigtriangleup T [/tex]
[tex] Q_{water} = 10 \times 4.184 \times (\bigtriangleup T)_{water} [/tex]
[tex] 100 = 41.84 \times (\bigtriangleup T) _{water} [/tex]
[tex] (\bigtriangleup T)_{water} = 2.39 C [/tex]
Final temperature of water = 2.39 + 25 = 27.39 °C
[tex] Q_{copper} = 10 \times 0.386 \times (\bigtriangleup T)_{copper} [/tex]
[tex] 100 = 3.86 \times (\bigtriangleup T) _{copper} [/tex]
[tex] (\bigtriangleup T)_{copper} = 25.9 C [/tex]
Final temperature of copper = 25 + 25.9 = 50.9 °C
From the above example we can see that when we supply the same amount of energy to the substances which are at the same initial temperature, the final temperature varies largely. This is due to the fact that they have different heat capacities.
This is the reason why metals become hot faster as they have small heat capacity values.
And therefore we can say that energy impact the temperature of different substance differently because they have different heat capacity values.
