Jason is investigating how energy from the Sun drives convection in the
atmosphere. He wants to draw a diagram showing what happens to air
when it is heated by the Sun during the process of convection. Which
diagram should he draw?
A He should draw a diagram that shows cool air in Earth's
atmosphere rising.
B He should draw a diagram that shows cool air near Earth's
surface rising.
C He should draw a diagram that shows warm air in Earth's
atmosphere sinking.
D He should draw a diagram that shows warm air near Earth's
surface rising.
Living creatures generally have a higher temperature than their environment. Explain why this makes sense.
give 4 examples for convection and radiation and explain your answers.

- Give some everyday examples of the transport of heat by convection and by radiation.arrow_forwardWhich of these is NOT a correct explanation for how convection works? Hotter fluids rise above colder fluids. Less dense fluids rise above denser fluids. Molecules spread apart as they heat, making the fluid less dense and causing it to rise. Colder fluids sink below hotter fluids. Less dense fluids sink below denser fluids.arrow_forwardSuppose that the Earth wore a snug steel belt around its equator (r = 6378 km). If everyone on Earth breathed on this steel belt simultaneously so that the belt's temperature increased by 2°C, how high off of the Earth would the belt be lifted? Hint: the coefficient of linear expansion of steel is 0.000012 Convert your answer from km to feet. 1 km = 1000 m 1 meter = 3.28 feetarrow_forward
- Difference between convection and conduction? Site some examples please.arrow_forwardWhat is external forced convection? How does it differ from internal forced convection? Can a heat transfer system involve both internal and external convection at the same time? Give an example.arrow_forwardMeteors sometimes strike Earth, converting most of their kinetic energy into heat. If a 90-kg meteor hits the ocean at 2.8x104 m/s and 84% of its kinetic energy goes into heating water, how many kg of water could it warm up by 4.8 °C? Give 1000 kg). your answer in metric tons (1 metric tonarrow_forward
- Solar heating of a house is much more efficient if there is a way to store the thermal energy collected during the day to warm the house at night. Suppose one solar-heated home utilizes a concrete slab of area 12 m² and 25 cm thick. If the density of concrete is 2400kg/m³, what is the mass of the slab?.arrow_forwardThe sun doesn’t shine as brightly in winter as it does in summer. This means that in winter you won’t generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures. Remember we use 2990kWh of electricity per year.arrow_forwardHow does human harness the heat beneath ground? Explainarrow_forward
- What is the difference between conduction and convection? (Choose TRUE or FALSE for each statement)a) Conduction occurs due to temperature gradient, while convection exists subjected to the both temperature and density differences.b) Conduction depends on the vibrated atoms in the medium, while convection depends on the atom separation in the medium.c)Conduction involves heat is transferred in one direction, while heat is circulated with convectionarrow_forwardOn the International Space Station, sensors have identified an interstellar gas cloud approaching the station. It seems to have temperatures in the millions of degrees K. The gas cloud has a very low density. Are you concerned about the heat from this cloud? Is it time to abandon the station? Discuss your answer, focusing on the difference between temperature and heat. Please type answer no write by hend.arrow_forwardBob heats up a bottle of milk for his baby, Jill, every morning. Jill will only drink the bottle if it is at 98 degrees. So Bob places the bottle in a cup of hot water (170 degrees). The bottle starts off at 35 degrees. After 2 minutes the bottle is 80 degrees. Use Newton's heating-cooling law, that the rate of change in the temperature, H, is proportional to the difference between the object and the surrounding temperature, to determine how long Bob should leave the bottle in the hot water. Assume that the water stays at 170 degrees.arrow_forward
