Chris has two tanks of helium gas. She wants to find out which tank has the most gas in it ,so she can blow up balloons for a party. Chris thinks that measuring the masses of the two tanks will identify which on contains the most gas. Will comparing the mass of the tanks help Chris know which one has the most gas in it? explain why or why not

Can smoke be transformed into liquid or used as energy or both?

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
