A glass flask has a capacity of 60cm3 at 12°c CALCULATE the capacity of the flask at a temperature of 50°c if the glass has linear cofficient of 9×10

Answer 1

The formula to calculate the change in volume of a material due to a change in temperature is:

ΔV = V₀ * β * ΔT

Where:
ΔV = change in volume
V₀ = initial volume (60 cm³)
β = linear coefficient for glass (9 x 10^-6 / °C)
ΔT = change in temperature (50°C - 12°C = 38°C)

Substitute the values into the equation:

ΔV = 60 * 9 x 10^-6 * 38
ΔV = 0.02052 cm³

To find the final volume at 50°C:
Vf = Vi + ΔV
Vf = 60 + 0.02052
Vf = 60.02052 cm³

Therefore, the capacity of the flask at a temperature of 50°C is approximately 60.02052 cm³.
