Question

A chef is cooking with a 2000-gram stainless steel skillet. Stainless steel has a specific heat capacity of 0.450 J/(g *oC). How much heat energy is required to raise the temperature of the skillet from 25oC to 125oC?
Group of answer choices


44,000 Joules

90,000 Joules

22,500 Joules

855 Joule

Answer 1

Answer:

Q = 90,000 J

Explanation:

Given data:

Mass skillet = 2000 g

Specific heat capacity = 0.450 J/g.°C

Energy required to raise temperature = ?

Initial temperature = 25°C

Final temperature = 125°C

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 125°C - 25°C

ΔT = 100°C

Q = 2000 g × 0.450 J/g.°C × 100°C

Q = 90,000 J
