Te is the correct ok is this
Answer:
(a) 3.38 Litres (b) $3.00
Explanation:
Q=Quantity of Heat required to make the cup of tea
Q = mcΔФ
m = mass of water
c= Specific capacity of water, 4.184 J/g/° C
p = density of water, 1g/mL
v = volume of water for tea, v= 1L or 1000mL
ΔФ= Change in Temperature , T₂ -T₁, T₂= 100°C, T₁=20°C
m = 1 g/mL x 1000 mL
= 1000g
Q= 1000 x 4.184 (100-20)
= 1000 x 4.184 x 80
= 334,720J
Number of moles of propane required = Q/ heat of combustion
= 334,720/ 2220000
= 0.150774 moles
At STP, 1 mole of every gas occupies 22.4 dm³
0.150774 moles of propane will occupy = 0.150774 x 22.4
= 3.3773376 dm³
= 3.3773376 Litres
≈ 3.38 Litres
If the cost per litre of propane is 88.9cent or $0.889
The total cost of propane for the tea will be = 0.889 x 3.38
= $3.00482
≈ $3
Answer:
A biome is an area of the planet that can be classified according to the plants and animals that live in it. Temperature, soil, and the amount of light and water help determine what life exists in a biome. A biome is different from an ecosystem. ... Some use broad classifications and count as few as six biomes.
