A 370-g sample of an unknown (nongaseous) material experiences a 24.0°C increase in temperature after absorbing 1.24 x 103) of energy. (a) What is the specific heat of this material? 3400

It takes 360 kJ to keep a 100 watt light bulb wont burn out,for how many years could the energy of the defect of 1 mole of 14C keep a 100-W light bulb burning?

The subject is Mechanics of Deformable Bodies

A gas contained in a vertical cylindrical tank has a volume of [10 + (162/100)] m3. The gas receives a paddle work of 7.5 W for 1 hours. If the density of the gas at the initial state is 1.5 kg/m3, determine the specific heat gain or loss if the specific internal energy of the gas increases by [(K/10) + 5] kJ/kg .

A man of weight 600 N is standing on the top of a building of height 10 m, the energy possessed by the man is Select one: O 6000 Nm O 60 Nm O 58800 Nm

A sample of iron absorbs 63.2 J of heat, upon which the temperature of the sample increases from 20.9°C to 29.6C. If the specific heat of iron is 0.450 Jig-K, what is the mass (in grams) of the sample? 16.1 g O 16.1g O 3.27 g 0.0619 g 3.92 g Submit Previous Answers Request Answer
