Calculate the heat, in kilocalories, that is absorbed if 183 g of ice at 0.0 ∘c is placed in an ice bag, melts, and warms to body temperature of 37.0 ∘c. the heat of fusion for water is 80. cal/g, or 334 j/g. the specific heat for water is 1.00 cal/g∘c, or 4.184 j/g∘c.

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.

Which sentences describe point source pollution? in this type of pollution, the source of the pollution is single and easily identifiable. when runoff water from the melting of snow mixes with debris, it creates pollution. the runoff water, mixed with pollutants, reaches large areas with disastrous effects. alternatively, when a wastewater treatment plant releases harmful chemicals into a stream, the chemicals pollute the stream water because they are not treated for safety.
