Using the combined gas law, calculate the following. also, what other law could you have used to solve this problem?

some teenagers think that their parents are “full of hot air.” your mom inhales 4 liters of air with a temperature of 20 degrees celsius. since you think she is full of hot air, this temperature must increase while the air is in her lungs. if this air heats up to 37 degrees celsius, what is the new volume of the gas?

(note that 37 degrees celsius is 98.6 degrees fahrenheit, which is normal body temperature! ) remember to pay close attention to the units of temperature before beginning your calculations

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

Will a solution form when the solvent and solute are both nonpolar? a. not likely b. never c. most likely
