Microwave ovens emit microwave energy with a wavelength of 12.7 cm. what is the energy of exactly one photon of this microwave radiation?

The energy of a photon is equal to the  product of planck's constant,h and speed of light,c over the wavelength,y. Hence, e=h*. h is equal to 6.6261*10^-34 Js, c is equal to 3*10^8 m/s and y= 12.7 cm or 0.127 m. Substituting, energy is equal to 1.5652*10^-24 Joules.

Idk the answer sorry

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
