Question 1 Correct 5.00 points out of 5.00 Talc is a mineral with low conductivity for heat and electricity which is not attacked by acid. It is used in talcum powder and face powder. Suppose a sample of talc weighs 13.65 g with a density of 1.75 g/cm3 in mineral oil. If this same sample of talc in air weighs 35.97 g, assuming no volume change, what is the density of the talc sample in air? Select one: A. 2.44 g/cm3 B. 2.82 g/cm3 C. 1.61 g/cm3 D. 4.61 g/cm3 E. 2.63 g/cm3 Question 2...

Quantum Physics-2024 Blackbody Radiation - ️️ - Radiation properties are independent of the material. The maximum of the distribution shifts to smaller wavelengths as the temperature is increased. The total power radiated increases with the temperature. One of the outstanding exceptions that classical physics could not explain, dubbed the "ultraviolet catastrophe" by Paul Ehrenfest. Blackbody - ️️ - Has the ideal property that it absorbs all the radiation falling on it and refle...
