(Linear expansivity of steel = 1.1x10-5 0C-1 Determine the cubic expansivity of the metal?ġ0).A square sheat of steal has a side of 15cm at 00 C. If the pressure remain constant at what temperature will its volume be 150cm3?ĩ).The volume of a small piece of metal is 5.000cm3 at 200C and 5.014cm3 at 1000C. Assuming the temperature is kept constantĦ).How much heat is needed to melt 1.5kg of ice and then to rise the temperature of the resulting water 500c?ħ).How much heat is given out when 50g of steam at 1000c cool to water at 280c? (specific latent heat of vapourization of water =2.3x106Jkg-1)Ĩ).Some hydrogen gas has a volume of 200cm3 at 150c. Determine its volume when its pressure is 10Nm-2. How much will it expand when heated from 100c to 500c (linear expansivity of Iron = 1.2x10-5 0c-1)Ĥ).The quantity of heat required to change 1kg of mass of a solid at its melting point to liquid at the same temperatureĥ).Under a pressure of 14Nm-2, some air has a volume of 1.5m3. Sample of physics101 questions 1).The amount of heat required to change the state of substance without change in temperature is _Ģ).The reverse process of vapourization is _ģ).An iron rail is 20m long. All you need to do is to devote quality time to study the PHY101 Past Questions in PDF Format and watch yourself change the narrative by scoring better than you expected in the examination. We provide the correct answers in order to save your time. We bring all the questions for many years and put them together but we indicate the specific years of their occurrence. Normally, the PHY101 Past Questions in PDF Format is in a multiple-choice question, theory and practicals because it is a pure science subject.
