How much heat is required to heat a 5.0 g pyrex glass dish (c=0.176 J/gC) from 23 degrees C to 65 degrees C?

Q = 36.96 j

Explanation:

Given dа ta:

Mass of pyrex glass dish = 5.0 g

Specific heat capacity = 0.176 j/g.°C

Initial temperature = 23 °C

Final temperature = 65°C

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

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 = 65°C - 23 °C

ΔT = 42°C

Q = 5 g * 0.176 j/g.°c * 42°C

Q = 36.96 j
