The specific heat of mercury is 140 J/kg K. Its heat of vaporization is 2.06 x 105 J/kg. How much heat is needed to heat 1.0 kg of mercury metal
from 10.0o C to its boiling point and vaporize it completely? The boiling
point of mercury is 357o C.

A. 49,000 J
B. 260,000 J
C. 310,000 J
D. 360,000 J

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

What instrument is used to measure liquid volume?
