Suppose that a commercial espresso machine in a coffee shop turns 1.50 kg of water at 22.0? c into steam at 100? c. if c=4187j/(kg? ? c) and hv=2,258kj/kg, how much heat q is absorbed by the water from the heating resistor inside the machine? assume that this is a closed and isolated system. express your answer in joules to three significant figures. q = j

Total heat required will be 555.756 KJ

Explanation:

We have given mass of the water m = 1.50 kg

Temperature is changes from to steam

Specific heat is given as c = 4718 J/kg

So amount of heat for changing the temperature from to

Heat of vaporization is given

So the amount of heat required to vaporize water

So total heat

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
