Answer:
1. the sun is used to directly do a job
2. The bimetallic strips are used to control the temperature of appliances . As the temperature increases beyond normal or the temperature decreases beyond normal . Due to this strip the , appliance is disconnected . Which keeps the appliance safe from damage .It is used in water Geysers and electric iron or Refrigerators.3. 1. heat engine ~~ •a machine that converts the internal energy of a fuel into mechanical energy.2. heat pump ~~ •an appliance that extracts heat energy from one source and deposits itelsewhere.3. Boiler ~~ •a heating appliance that uses heat energy released from fossil fuels to warm water for use in radiant orconvection heating systems.4. Thermostat ~~ •an appliance that controls the maintenance temperature of a heatingsystem
4. 66.7%
5. liquid based substance.
Explanation:
Answer:
heat energy obtained directly from the Sun: active solar heat
a liquid-based substance used to carry heat energy through a heating system: hydronic
an attachment which allows exhaust gases to be chemically broken down to release more energy: catalytic combustor
a welded strip of two metals with different thermal expansion properties: bimetallic strip
a heating appliance that uses heat energy released from fossil fuels to warm air for use in forced-air systems : furnace
