Answer:
205.20 kJ/kg is the heat of fusion of copper in kJ/kg.
Explanation:
Heat of fusion is defined as heat provided to specific mass of solid to change its state from solid to liquid.
Amount of heat required to convert solid copper into liquid = Q = 2995.9 kJ
Mass of copper m = 14.6 kg
Heat of fusion of copper = ![\Delta H_{fus}=\frac{Q}{m}](https://tex.z-dn.net/?f=%5CDelta%20H_%7Bfus%7D%3D%5Cfrac%7BQ%7D%7Bm%7D)
![=\frac{2995.9 kJ}{14.6 kg}=205.20 kJ/kg](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2995.9%20kJ%7D%7B14.6%20kg%7D%3D205.20%20kJ%2Fkg)
205.20 kJ/kg is the heat of fusion of copper in kJ/kg.
Answer:
= 27Ω
Explanation:
The voltage of a device = Resistance × Current
V=RI
Making R the subject of the formula we have R= V/I
Thus resistance = Voltage/ Current
V= 81 V
I = 3 A
Using these values in the formula for resistance we can then find the resistance of the device as follows.
R = 81 V/ 3 A
= 27Ω
