The heat transferred is -30J
When the gas undergoes compression, work is done on the gas and its internal energy increases.
According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW

The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.
Therefore, the heat given to the gas is given by,

Thus, an amount of heat equal to 30 J flows out of the system.
Protons and neutrons are both inside the nuclei of the atom while the electrons are spinning around. they also make up the mass of the atom.
protons are positively charged while neutrons are neutral.
Protons and electrons are alike in the number while they are opposites in the charge because protons are positive while electrons are negative. Their quantity makes up the atomic number for an element.
<span> Space satellites, laser beams, mirrors</span> are used to calculate the distance a continent has moved in a year.
Therefore, your correct answer would be "all of the above".
Because they have different measurements and weight and mass and some measurements are the same
