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

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

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
