Can someone help me with these gas laws problems? I need help seeing it step by step. I've been trying but my answers don't make any sense!
1) A plastic syringe with a movable plunger is capped, trapping 13.2 mL of gas. If this gas exerts a pressure of 1.03 atm when the temperature is 24.8OC, determine the variable that changes and calculate its new value if the syringe is placed in a beaker of cold water with a temperature of 5.82OC.
Consider a helium balloon inside a parked car on a hot day where the temperature is 72.0OC and the pressure is 1.02 atm. When the balloon is taken outside where the temperature is 34.0OC its volume is measured as 2.21 L. What is the change in the volume of the balloon compared to when it was in the car?

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
