I believe it’s because they are trying to find other things that won’t pollute the environment as much, and they are also doing this because we are trying to reduce green house gas. Sorry if i’m wrong :(
Yeeeeeeeeeeeeeeeeeeeeeees
Here we have to get the temperature and pressure at which helium gas mostly behaves as ideal gas.
Helium (He) behave most like an ideal gas upto 24K temperature and 0 atm pressure.
The deviation of a real gas to ideal gas occurs at high temperature and low pressure.
The deviation of ideal gas to real gas occurs on taking into account the van der waals' force of attraction between the gas molecules. Now, the van der waals' interaction depends upon the polarisibility of the gas molecule.
As helium (He) is non-polarisable and very small (atomic number 2) it mostly behaves as ideal gas upto 24K temperature and 0 atm pressure.
Although the deviation from the ideal gas behavior to real gas is not so prominent at little high temperature also. Upto 50K it mostly behaves like an ideal gas.
The chemical energy, which is a type of kinetic energy explains the type of energy present in the wheels of a moving bus.
Explanation:
Kinetic Energy is the energy possessed by an object by virtue of its motion.
Kinetic Energy is present in every moving object. A moving bus, train,flying airplane, walking , running etc are some examples of Kinetic Energy.
Kinetic Energy is classified into two parts Rotational Kinetic Energy and vibrational Kinetic energy.
Kinetic energy depends on two things , the mass and the velocity of the object.
In the above example , in a moving bus,the wheels of the bus are also moving. So with motion, Kinetic energy gets formed.
Answer:
Change in temperature = ΔT = 26.8°C
Explanation:
Given data:
Heat absorbed = 600 j
Mass = 25.0 g
Specific heat capacity = 0.897j /g°C
Change in temperature = ΔT= ?
Solution:
Formula:
q = mcΔT
600 j = 25.0 g ×0.897 j/g°C×ΔT
600 j = 22.425 j/°C×ΔT
ΔT = 600 j /22.425 j/°C
ΔT = 26.8°C
