The specific heat of liquid mercury is 140 J/kgC. When 1 kg of solid mercury at its melting point of -39C is placed in a 0.5 kg aluminum calorimeter filled with 1.2 kg of water of temperature 20C, the mercury melts and the final temperature of the combination is 16.5 C. What is latent heat of mercury

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

i believe the answer is electric potential.

explanation:
