(c) Heat flows from a body with low temperature to a body with higher temperature.
(d) Ice is a good conductor of heat.

(Liquids conduct better heat than solids.
(3) A polished, silvery surface is a good absorber and a bad radiator of heat.
(h) All solids expand by the same amount when heated through the same temperature range

Answer 1

The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

Water at higher temperature feels more hot.

Because, body at higher temperature has higher average KE of molecules and body at lower temperature has lower average KE of molecules. When two bodies having higher temperature and lower temperature are keep in contact, the body at higher temperature shares their energy to molecules at lower temperature.

Answer 2

Land breeze, a local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water. ... Since the surface flow of the land breeze terminates over water, a region of low-level air convergence is produced.

Sea breeze, a local wind system characterized by a flow from sea to land during the day. Sea breezes alternate with land breezes along the coastal regions of oceans or large lakes in the absence of a strong large-scale wind system during periods of strong daytime heating or nighttime cooling.
