Assume that the eccentricity of Earth’s orbit increases from 0.017 to 0.12. The point of aphelion would now be . Consequently, the amount of solar energy received on Earth at aphelion would .

Asample of neon occupies a volume of 375 ml at stp. what will be the volume of neon if the pressure is reduced to 90.0 kpa? a. 422 ml b. 422 l c. 333 ml d. 333 l

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
