Question

A syringe containing 12.0 mL of dry air at 25 C is placed in a sterilizer and heated to 100.0 C. The syringe is sealed, but the plunger can move and the volume can change. What is the volume of the air in the syringe at 100.0 C, assuming no change in pressure?

Answer 1

15.01 Liters

Step-by-step explanation:

T₁ = Initial temperature = 25°C = 298.15 K

T₂ = Final temperature = 100°C = 373.15 K

V₁ = Initial volume = 12 mL

Here, pressure is constant so we apply Charles Law

`(V_1)/(T_1)=(V_2)/(T_2)\\\Rightarrow {V_2}=(V_1)/(T_1)* T_2\\\Rightarrow {V_2}=(12)/(298.15)* 373.15\\\Rightarrow {V_2}=15.01 L`

∴ Final volume at 100°C is 15.01 Liters.
