Question

1. active solar heat

heat energy obtained directly from
the Sun
2. bimetallic strip
3. catalytic combustor
a welded strip of two metals with
different thermal expansion properties
an attachment which allows
exhaust gases to be chemically broken
down to release more energy
a liquid-based substance used to
carry heat energy through a heating
system
a heating appliance that uses heat
energy released from fossil fuels to
warm air for use in forced-air systems
4. furnace
5. hydronic

Answer 1

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.

Step-by-step explanation:

Answer 2

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
