Why does the troposphere vary in thickness? Group of answer choices

Water vapor weighs down troposphere and less water vapor cause it to rise higher.

Air turbulence in the troposphere varies the altitude.

Warmer air dissipates into the stratosphere. Cooler air is trapped in the troposphere.

Cooler air contracts lowering the height, warmer air expands raising the altitude.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
