A 1.00 kg copper bar is heated to atmospheric pressure so that its temperature increases from 20 ° C to 50 ° c. The density of copper is 8.92 x 103 kg and the coefficient of volumetric expansion is 4.5 x 10-5 (C0) -1 Determine the change in volume of the copper bar. (Remember that p = m / V)
I need help with the missing equation: Analyze Find the work done on the copper bar using WPVf- V): Express the change in volume using Δν = ßvAT and that β = 3α (Use the following as necessary: α, P, V., and ΔΤ. Do not substitute numerical values; use variables only.):
A 0.80 kg block of aluminum is heated at atmospheric pressure so that its temperature increases from 22.0°C to 40.0°C. (a) Find the work done on the aluminum. mJ (b) Find the energy added to it by heat. kJ (c) Find the change in its internal energy. kJ
A spray can containing a propellant gas at twice atmospheric pressure (202 kPa) and having a volume of 119.00 cm is at 27°C. It is then tossed into an open fire. (Warning: Do not do this experiment; it is very dangerous.) When the temperature of the gas in the can reaches 195°C, what is the pressure inside the can? Assume any change in the volume of the can is negligible. SOLUTION Conceptualize Intuitively, you should expect that the pressure of the gas...
A lead block of mass 7.0 kg is originally at a temperature of 15°C and 1 atm. It is then heated to a temperature of 64°C without any change in pressure. The specific heat of lead is 128 J/(kg - °C), its density is 1.13 x 104 kg/m3, and the coefficient of linear expansion is 29 x 10 -6/oC (a) Determine the work done by the lead block (b) How much heat energy is transferred during this process? J (c)...
One mole of H20( is supercooled to-5.00°C at 1 bar pressure before freezing at that temperature. Calculate ASys, ASum, and ASeotal for this process. Is it spontaneous? CPm (H20, 1)- 75.3 J/mol.K CPm (H20, s)-37.7 J/mol.K AHfusion 6.008 kJ/mol Hint: remember that ASs is computed using q along a reversible path, while ASur is computed using the actual heat transfer during the freezing. For the following equilibrium reaction: Here is an ICE table, starting from no moles of pure 0z...
