The final temperature of copper is 155.43°C.
Step-by-step explanation:
The formula to apply is Q=m*Δt*c where ;
Q=heat energy, m=mass, c=specific heat capacity and Δt= change in temperature
Given that Q=54 calories , m=4.50 g and c=0.092 cal/g°C
In this question find Δt then ,the final temperature.
Δt=Q/m*c
Δt=54/4.50*0.092 =130.43°C
To find final temperature, apply the formula;
Δt=Final temperature - Initial temperature
130.43°C=Final temperature-25°C
130.43°C+25°C=Final temperature
155.43°C

The final temperature of copper is 155.43°C.
We use the formula for the heat energy
The formula to apply is [tex]Q=m*\Delta t*c[/tex]
Where;Q=heat energy, m=mass, c=specific heat capacity and Δt= change in temperature
Given that Q=54 calories , m=4.50 g and c=0.092 cal/g°C
first we have to find the Δt
[tex]\Delta t=Q/(m\times c)[/tex]
[tex]\Delta t=54/4.50*0.092 =130.43^{0}C[/tex]
Next we have to find the final temperature so
[tex]\Delta t=Final temperature - Initial temperature[/tex]
plug the value of delta t and initial temperature in above formula we get,
[tex]130.43=Final temperature-25[/tex]
[tex]130.43+25=Final temperature[/tex]
[tex]155.43=final temperature[/tex]
Therefore ,The final temperature of copper is 155.43°C
