**1. Homework Statement**

At the surface, where the temperature is 27 °C, the volume of air in Dan’s diving bell is 2 metres cubed. When he descends to a depth of 10 m the pressure doubles and the temperature drops to 7 °C. What volume of air does Dan have in his diving bell now?

**2. Homework Equations**

P1 x V1/T1 = P2 x V2/T2

**3. The Attempt at a Solution**

P1= ? P2= ?

V1= 2 metres cubed V2= ?

T1= 27 °C (300 Kelvin) T2= 7 °C (280 Kelvin)

Im having trouble finding out P1 and therefore I can't find out P2 and V2!

Please help me.

Thanks
