What mass of LP (liquid propane) gas is required to heat 1.5 L of water from room temperature (25 °C) to boiling (100 °C)? Assume that during heating 85% of the heat emitted by the LP gas combustion goes to heating the water and the rest is lost to the surroundings. Note that LP has a heat of combustion of -2044 kJ/mol

Tropical easterlies is mostly likely your answer correct me if i’m wrong

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
