Consider an ideal gas with an absolute temperature of T1. To what absolute temperature would the gas need to be heated to double its pressure? Express the answer in terms of T1.

To double the pressure, the temperature has to be 2*t1 K

Explanation: Gay-Lussacs law states: for a constant mass of gas held at constant volume, Pressure is proportional to absolute temperature (degrees K)

p1/t1 = p2/t2

we have p1/t1 = 2*p1/t2—> t2 = 2*p1*t1/p1 —> 2*t1

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
