3. Explain why, for a gas, the specific heat at constant volume has a different value
from the specific heat at constant pressure.
An ideal gas is contained in a cylinder fitted with a piston. Initially the temperature of the
gas is 15℃. If the mass of the gas is 0.035 kg, calculate the quantity of heat energy
required to raise the temperature of the gas to 150 ℃ when:
(a) The piston is fixed;
(b) The piston moves and the pressure is constant.
For the gas, 𝑐𝑣 = 676 J/kg-K and 𝑐𝑝 = 925 J/kg-K.
There are 100 bunnies living on an island on November 7, 2006. The net birth rate is 1.2 baby bunnies/ bunny-year, 0.85 bunnies/bunny-year go to bunny heaven annually. Numerous bunny tourists decide to stay on the island—so that the net immigration rate is 0.45 bunnies/bunny-year, and 0.12 bunnies/ bunny-year leave for better-tasting alfalfa. How many bunnies are there on November 6, 2007? How many bunnies are there on the island on November 6, 2016? Use the Human Population Dynamic Model. State any assumptions inherent in this model.
The graph generated is a polynomial (i.e. the quadratic equation: ax2+bx+c=0) graph that follows the form:
The dependent (y) variable in your graph equation is the displacement (Δd) and the independent (x) variable is the time interval (Δt). Based on this information, what would be the:
- A) initial velocity of the cart when the software started recording data?
- B) acceleration of the cart?;
- C) displacement of the cart when the software started recording data?
A gas is confined to a cylinder under constant atmospheric
pressure, as illustrated in Figure 5.4. When the gas undergoes
a particular chemical reaction, it absorbs 824 J of heat from
its surroundings and has 0.65 kJ of P–V work done on it by
its surroundings. What are the values of ∆H and ∆E for this
