Atank of oil has a mass of 50 slugs.
a) determine its weight in pounds and in newtons at the earth’s surface.
b) what would be its mass (in slugs) and its weight (in pounds) if located on the moon’s surface where gravitational attraction is 1/6th that at the earth’s surface?

What are chlorofluorocarbons and what impact do they have on the atmosphere?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3
