The density of gasoline is 7.30 x 102 kg/m³ at 0°C. Its average coefficient of volume expansion is 9.60 x 10-4 (°C)-1, and note that 1.00 gal = 0.00380 m³. (a) Calculate the mass of 11.8 gal of gas at 0°C. (Give your answer to at least two decimal places.) kg (b) If 1.000 m³ of gasoline at 0°C is warmed by 19.3°C, calculate its new volume. (Give your answer to at least two decimal places.) 7m³ (c) Using the answer to part (b), calculate the density of gasoline at 19.3°C. (Give your answer to at least three significant figures.) kg/m³
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
