Which method of heat transfer transmits heat from the lower layers of air to the upper layers of air?

conduction, because the warm and cool air particles move from their positions
conduction, because medium particles move and bump into each other during heat transfer
convection, because warm air over land rises up and is replaced by upper layers of cooler air
convection, because electromagnetic waves carry the warm air over land to the cooler layers of atmosphere

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Which statement best describes the function of enzymes?
