Answer:
The temperature of the substance with the lower specific heat will increase more than the one with a higher specific heat
Explanation:
The increase of temperature of a substance is given by:
where
Q is the amount of heat absorbed by the substance
m is the mass of the substance
is the specific heat capacity of the substance
In this problem, we have two substances with same mass m, that absorb the same amount of heat Q. We see from the formula that the increase in temperature is inversely proportional to the specific heat: therefore, the substance with lower specific heat will have a greater increase in temperature than the substance with higher specific heat.
Answer:
The inside Pressure of the tank is
Solution:
As per the question:
Volume of tank,
The capacity of tank,
Temperature, T' = = 299.8 K
Temperature, T = = 288.2 K
Now, from the eqn:
PV = nRT (1)
Volume of the gas in the container is constant.
V = V'
Similarly,
P'V' = n'RT' (2)
Also,
The amount of gas is double of the first case in the cylinder then:
n' = 2n
where
n and n' are the no. of moles
Now, from eqn (1) and (2):
Answer:
effeciency n = = 49%
Explanation:
given data:
mass of aircraft 3250 kg
power P = 1500 hp = 1118549.81 watt
time = 12.5 min
h = 10 km = 10,000 m
v =85 km/h = 236.11 m/s
kinetic energy
kinetic energy
gravitational energy
total energy
effeciency n = = 49%
