If you throw a raw egg against a wall, you'll break it, but if you throw it with the same speed into a sagging sheet it won't break. why? 1. the sheet is much slicker than the wall. 2. the breaking egg causes a larger impact time, decreasing the force. 3. the impact time when the egg strikes a sagging sheet is long, so the impact force is small. 4. the velocity of the egg decreases faster in the sheet than on the wall.

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

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2
