Which of the following is true of gases? Gases are not easily compressed because of expansion and limited space between particles. Gases mix easily because of their high kinetic energy and low intermolecular forces. Gas particles diffuse easily because of their low fluidity and high intermolecular forces. Gas particles spread out to fill a container because of their high density and high kinetic energy.

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
