Question

A light, plastic sphere with mass m = 9.00 g and density ρ = 5.00 kg/m3 is suspended in air by thread of negligible mass.

a)What is the tension T in the thread if the air is at 5.00∘C and p = 1.00 atm? The molar mass of air is28.8 g/mol.

b)How much does the tension in the thread change if the temperature of the gas is increased to 35.0

∘C?Ignore the change in volume of the plastic sphere when the temperature is changed.

Express your answer with the appropriate units. Enter positive value if the tension increases and negative value if the tension decreases.
