Amal is carrying out an experiment investigating which colours are the best absorbers of infra red radiation. He puts 4 cans of water under a heat lamp and measures the temperature change after 20 minutes.Which can will be at the highest temperature?I DON'T KNOWSUBMIT ANSWERLearning MaterialChoose your materialCENTURY ExplainsVideoEnergy Transfers by Heating: RadiationQuestionQuestionQuestionQuestionQuestionQuestionQuestionQuestionQuestionSummary

Four test tubes are filled with 10 ml of water each, and placed 10 cm away from the light bulb.The initial temperature of each test tube is measured.The tubes are then left in full exposure of the reflected rays.The temperature of each tube is taken every 5 minutes for 15 minutes.Which tube will experience the second highest rise in temperature at the end of the experiment?A- Matt BlackD- Shiny BlackC- Shiny SilverB- Matt White

Which of the following does NOT occur when the temperature of a red-hot object increases?The amount of electromagnetic radiation which it emits increases at all wavelengthsIt emits more visible lightThe potential energy of the particles which make up the object decreasesThe shortest wavelength of the radiation which it emits decreases2The radiation produced by an infrared laser has a wavelength of 1054 nm.  Convert this wavelength to metres.1.054 × 10-9 m1.054 × 10-3 m1.054 × 10-12 m1.054 × 10-6 m3What happens to an object when it emits energy faster than it absorbs energy?Its temperature decreasesIts temperature remains constantIts temperature increasesIt is impossible to say what happens to the temperature of the object without knowing the specific heat capacity of the material from which it is made4Which of the following statements is incorrect?The intensity of the radiation which we receive from the Sun can be measured in joules per square metreThe intensity of the radiation which we receive from the Sun can be measured in watts per square metreThe intensity of the radiation which we receive from the Sun can be measured in joules per second per square metreThe intensity of the radiation which we receive from the Sun is higher at the Equator than it is at the poles5Which of the following statements is incorrect?Some of the radiation from the Sun which reaches the Earth is reflected by clouds and atmospheric gasesAll of the infrared radiation from the Sun which reaches the surface of the Earth is absorbedIf the overall rate at which energy from the Sun is absorbed by the Earth is greater than the overall rate at which energy is emitted into space, the temperature of the Earth will increaseIf the overall rate at which energy from the Sun is absorbed by the Earth is less than the overall rate at which energy is emitted into space, the temperature of the Earth will decrease
