Answer:
Explanation:
7.0 - 4.0 = 3.0 kg water
3.0 kg(2.26 x 10⁶ J/kg = 6.78 x 10⁶ J
220 V(15 A) = 3300 W
1 W = 1 J/s
6.78 x 10⁶ J / 3300 J/s = 2054 s
2054 s / 60 s/min = 34 min
It will take b) 34 min to dry the clothes
What is an electrical energy ?
An electric energy is amount of work done or energy consumed in a given amount of time
water absorbed by wet cloth = mass when it was wet - mass when dried
7 - 4 = 3 kg
latent heat of vaporization = 2.26 * 10 ^6 j/kg
To vapor 3kg water heat required = 3 * 2.26 * 10 ^6 j/kg = 6.78 * 10 ^ 6 j/kg
Power = voltage * current
220 * 15 = 3300 W
energy = power * time
time = energy / power
= 6.78 * 10 ^ 6 j/kg /3300 W
= 2054.54 sec
or 2054.54 / 60 = 34 min (app)
It will take b) 34 min to dry the clothes
