A balloon has a volume of 3 L at a temperature of 298 K and a 1 atm. What will the temperature be if the volume is 1.5 L and the pressure is increased to 4 atm?

596 K

Explanation:

cross multiply

divide by 1 atm and 3 L to isolate the variable

cancel out units

multiply numerator and denominator

divide

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
