How much energy (in Joules) is required to convert 80 grams of ice at −46 °C to liquid water at 29 °C? (The specific heat of ice = 2.10 J/g°C; the specific heat of water = 4.184 J/g°C; the heat of fusion = 333 J/g°C).

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?
