Answer:
70,219.4 Joules
Step-by-step explanation:
To calculate the amount of energy required to heat a substance, we can use the following formula:
Q = m * C * ΔT
Where Q is the amount of heat energy required (in Joules), m is the mass of the substance being heated (in grams), C is the specific heat capacity of the substance (in J/g - °C), and ΔT is the change in temperature (in °C).
In this case, we want to find the amount of energy required to heat 706 g of nickel from 25°C to 300°C, given that the specific heat capacity of nickel is 0.444 J/g - °C.
First, we need to calculate ΔT, which is the difference between the final temperature (300°C) and the initial temperature (25°C):
ΔT = 300°C - 25°C = 275°C
Next, we can plug in the values we know into the formula:
Q = m * C * ΔT
Q = 706 g * 0.444 J/g - °C * 275°C
Q = 70,219.4 J
Therefore, it would require approximately 70,219.4 Joules of energy to heat 706 g of nickel from 25°C to 300°C.
