A 750 watt hairdryer is used for 60 seconds. how many joules of energy are used?
daser333 [38]
We know, Power = Energy / time
Here, P = 750 Watt
t = 60 sec

Substitute their values, 
750 = E / 60
E = 750 * 60
E = 45,000 J

In short, Your Answer would be 45,000 Joules

Hope this helps!

Say that you are in a large room at temperature TC = 300 K. Someone gives you a pot of hot soup at a temperature of TH = 340 K.
lora16 [44]

Answer:

Explanation:

Heat energy given out by the soup

= C_v  x ( t₂ - t₁ )

= 33 x ( 340 - 300)

= 1320 J

This heat is given to Carnot engine . Efficiency of engine

= (340 - 300 ) / 340

= 40 / 340

2 / 17

This fraction of total heat given is converted into useable work by the engine.
