After an electric sign is turned on, the temperature of its glass goes from 23.5°C to 65.5°C. The sign’s glass has a mass of 905 grams, and the specific heat capacity of the glass is 0.67 joules/gram degree Celsius. How much heat did the glass absorb? Type the correct answer in the box. Use numerals instead of words. Express your answer to the correct number of significant figures.

Iwll give extra points to who gets this for ! what type of reaction is this? ?

At room temperature what happens to the average kinetic energy of the molecules of a solid, liquid, and a gas

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.
