if the thermal energy of a metal with specific heat capacity of 40joule\kgk is 15j find the thermal energy of another metal with the temperature if the specific heat capacity of the metal is 0.3j/ kgk
To find the thermal energy of the second metal, we need to know both the mass of the metal and the change in temperature. The equation for calculating thermal energy is:
Thermal Energy = mass x specific heat capacity x change in temperature
Given:
Specific heat capacity of the first metal (metal 1) = 40 J/kgK
Thermal energy of metal 1 = 15 J
We can rewrite the equation as:
Thermal Energy of metal 1 = mass of metal 1 x specific heat capacity of metal 1 x change in temperature of metal 1
Rearranging the equation, we have:
mass of metal 1 x specific heat capacity of metal 1 = Thermal Energy of metal 1 / change in temperature of metal 1
Now, we can calculate the mass of metal 1:
mass of metal 1 = Thermal Energy of metal 1 / (specific heat capacity of metal 1 x change in temperature of metal 1)
mass of metal 1 = 15 J / (40 J/kgK x change in temperature of metal 1)
Let's assume the change in temperature for metal 1 is ΔT1.
mass of metal 1 = 15 J / (40 J/kgK x ΔT1)
Now, let's move on to the second metal (metal 2).
Given:
Specific heat capacity of metal 2 = 0.3 J/kgK
Change in temperature of metal 2 = ΔT2
Using the same equation as before, we can calculate the thermal energy of metal 2:
Thermal energy of metal 2 = mass of metal 2 x specific heat capacity of metal 2 x change in temperature of metal 2
Rearranging the equation, we have:
mass of metal 2 x specific heat capacity of metal 2 = Thermal energy of metal 2 / change in temperature of metal 2
Now, we can calculate the mass of metal 2:
mass of metal 2 = Thermal energy of metal 2 / (specific heat capacity of metal 2 x change in temperature of metal 2)
mass of metal 2 = Thermal energy of metal 2 / (0.3 J/kgK x ΔT2)
So, to calculate the thermal energy of the second metal, we need to know the mass of the second metal and the change in temperature (ΔT2).
15 * 0.3/40
However I wonder what these metals are to have such different heat capacities.
If the thermal energy of metal with specific heat capacity of 40j/Kgk is 15j, find the thermal energy of another metal of the same temperature if the specific heat capacity of the metal is 0.3j/kgk
Well, let's first bust out our calculators and get to work!
Given that the specific heat capacity of the first metal is 40 J/(kg*K) and its thermal energy is 15 J, we can use the formula Q = mcΔT, where Q is the thermal energy, m is the mass of the metal, c is the specific heat capacity, and ΔT is the change in temperature.
Since we're only given the thermal energy, we can't directly find the temperature change. However, we can still figure out the thermal energy of the second metal if we know its mass and the specific heat capacity.
Now, if the specific heat capacity of the second metal is 0.3 J/(kg*K), we'll need its mass and temperature change to find the thermal energy. Without those values, I'm afraid I can't be of much help. But hey, you can still ponder the mysteries of the universe until you gather the missing information!
