The calculation is very simple; multiply the specific heat S by the amount of the material and the change in temperature. Since S = 0.450 J/g °C, the amount of heat that needs to be added in J is (0.450)(g)(∆T) = (0.450)(150)(5) = 337.5 J. Another way to express this ...
In physics, the heat transfer is the part of the energy transfer, where the energy transferred from a higher source to the lower source. To the transferred of energy from a lower source to the higher source, there is a need to provide extra work through some mechanical device. ...
1. Explain the meaning of the coefficient of linear expansion for a material. 2. How is \Delta L related to \Delta T? 3. Will \Delta L be the same regardless if the rod is hollow or solid? What is the lumped-heat-capacity system? In what conditions can the system be applied?
A great example for such a semiterrestrial landscape at the northwestern edge of the mining district is the Spree Forest (Spreewald), an inland delta of the Spree river with extensive bog lands and a unique cultural landscape, that is protected as UNESCO Biosphere Reserve since 1991. The LRE ...

EchoDelta said: I don't get why "Pump to wheel" is something that comes up in discussions about sustainability. If the process that brings power from the pump to the wheel is not sustainable (for example, an ICE emits CO2, so is not acceptable). And overall efficiency does matter, ...
When heat is provided to a material, it increases the rms velocity of the particles in the material, thereby increasing the temperature of the material.Answer and Explanation: When heat is provided to a material, generally the temperature of material increases. However, sometimes the temperature ...
If the internal energy of a thermodynamic system is increased by 350 J while 75 J of expansion work is done, how much heat was transferred and in which direction, to or from the system? What is the change in internal energy of a system in BTU if the system absorbs 125 J of heat and...
What is the quantity of heat absorbed by the 600 g water in the bath, in kilojoules? Delta T = 2.14 C, Specific heat H2O = 4.184 times 10^(-3) kJ/g*C. A beaker containing 250.0 g of water is heated with 1500.0 J of heat energy. If the temperature of the water...
What is the quantity of heat required to melt down completely 1 kg of ice at 30∘C? Calorimetry: The heat required to completely melt down the ice is the sum of heat required to bring down the temperature to the freezing point of water and the heat required...
