To make yourself some coffee, you put one cup of water (246 gg ) in a small pot on the stove. Part A What quantity of energy must be transferred thermally to the water to raise its temperature from 20 ∘C∘C to 100 ∘C∘C?

The heat required to raise the temperature of water is required.

The heat required is

m = Mass of coffee = 246 g

c = Specific heat of water = 4.184 J/g C

= Change in temperature =

Heat is given by

The heat required is

The required heat energy is .

Explanation:

The heat energy 'Q' required to raise the temperature of water is given by

where 'M' is the mass of water, 's' is the specific heat capacity of water and '' is the change of temperature.

Given, and we know that the specific heat capacity of water is .

Substituting the values in the above expression, the required heat energy is

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
