Answer:
20.25 W
Explanation:
Applying,
P = I²R.................... Equation 1
Where P = Power, I = current drawn by the test light, R = Resistance of the test light
From the question,
Given: I = 1.5 A, R = 9.00 Ω
Substitute these values into equation 1
P = (1.5²)(9)
P = 2.25×9
P = 20.25 W
Answer:
Fossil fuels, carbon dioxide, gases released from polluted waste, and gases released in the air that are trapped in our atmosphere
Explanation:
If the burner doesn't light after several strikes, turn the gas off at the source. Verify that you are generating sparks when striking the striker, and check that the barrel is all the way down and the needle valve is open by the specified amount. If these check out, the problem may be insufficient gas flow.
ΔH0 = -75.0 kJ
<span>Pressure, P = 43.0 atm </span>
<span>= 43 atm * 101325 Pa/1 atm </span>
<span>= 4356975 Pa </span>
<span>= 4356975 N / m2 </span>
<span>Volume change, ΔV = 2.0 L - 5.0 L </span>
<span>= -3.0 L </span>
<span>= -3.0 *10-3 m3 </span>
<span>Work done, w = - PΔV </span>
<span>= - (4356975 N / m2) (-3.0 *10-3 m3) </span>
<span>= 13070 N m </span>
<span>= 13070 J </span>
<span>= 13.07 kJ </span>
<span>We know that at consatnt pressure q = ΔH0 = -75.0 kJ </span>
<span>Also ΔE = q + w </span>
<span>= - 75.0 kJ + 13.07 kJ </span>
<span>= -61.93 kJ</span>
