The hydrogen gas used to make ammonia can be made from small hydrocarbons such as methane in the so-called steam-reforming process, run at high temperature and pressure. a. if 3.2 atm of methane at 21 °c are introduced into a container, to what temperature must the gas be heated to increase the pressure to 12 atm

temperature is 829.5 °C

Explanation:

given data

methane  = 3.2 atm

temperature = 21 °C  = 21 + 273 = 294 K

increase the pressure = 12 atm

to find out

what temperature must the gas be heated

solution

we know at constant volume

pressure is directly proportional to temperature

so

we can say

P(initial) / T(initial) = P(final) / T(final)    1

here P is pressure and T is temperature

put the value

3.2 / 294  = 12 / T(final)

T(final) = 12 × 294 / 3.2

T(final) = 1102.5 K

so T(final) =  1102.5 - 273

T(final) is 829.5 °C

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day
