Answer:

18kcal

Explanation:

Melting enthalpy of water: 80 cal/g

The melting enthalpy discribes how much heat is needed to melt a substance. So you get the heat by multiplying the mass of your substance with its melting enthalpy.

225g*18cal/g=18000cal=18kcal

Why is the sky blue ?
Andrews [41]

Answer:

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere.

Explanation:

Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.

Where are the physics in football
sasho [114]

Answer:

The branch of physics that is most relevant to football is mechanics, the study of motion and its causes.

Explanation:

When the ball leaves the punter's foot, it is moving with a given velocity (speed plus angle of direction) depending upon the force with which he kicks the ball. The ball moves in two directions, horizontally and vertically. Because the ball was launched at an angle, the velocity is divided into two pieces: a horizontal component and a vertical component.
