The oven draws 1100 w of power, and you have determined that it heats with an efficiency of 51%. using this information, determine the time t it would take to bring 240 ml of water from 25∘c to 100∘c . note that 4.2 j of energy is required to raise the temperature of 1.0 ml of water by 1.0∘c (the same as for the coffee above).

134.75935 seconds

Explanation:

m = Amount of water = 240 mL

c = Specific heat of water = 4.2 J/mL °C

=  Change in temperature =

t = Time taken

P = Power = 1100 W

E = Pt

Efficiency = 51 %

So, Energy = 0.51Pt

As energy is conserved

Q = 0

The it takes to raise the temperature is 134.75935 seconds

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
