Chemistry Challenge: Heat Gain by Nickel
How much heat is gained by nickel when 29.2 g of nickel is warmed from 18.3°C to 69.6°C?
What is the specific heat of nickel and how can we calculate the heat gained by nickel in this scenario?
Answer:
To find the heat gained by nickel, use the specific heat formula with the given mass, specific heat capacity of nickel, and temperature change to calculate that the nickel gains 668.2032 joules of heat.
The amount of heat gained by nickel when 29.2 g of nickel is warmed from 18.3°C to 69.6°C can be calculated using the specific heat formula: q = m × c × ΔT, where q is the heat gained, m is the mass of the nickel, c is the specific heat capacity, and ΔT is the change in temperature.
Substituting in the given values for the specific heat of nickel (0.443 J/(g · °C)), the mass of the nickel (29.2 g), and the temperature change (69.6°C - 18.3°C), we get:
q = 29.2 g × 0.443 J/(g · °C) × (69.6°C - 18.3°C)
Calculating this we find:
q = 29.2 g × 0.443 J/(g · °C) × 51.3 °C
q = 668.2032 J
The nickel gains 668.2032 joules of heat.
