The volume of a helium balloon in Los Angeles is 14.0 L. The temperature in Los Angeles is 25°C. Find the volume of the balloon in Death Values where the temperature is 52°C, with the pressure being the same in both places. Show your work.

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
