Answer:
Final Temperature is 310K
Explanation:
Given that:
Mass of O₂ gas = 2 kg
Pressure (P₁) = 100 kpa
Temperature (T₁) = 310K
We also have, ΔQ = ΔU + ΔW where ΔQ is the heat transferred into/out of the system, ΔW is the work done and ΔU is the change in internal energy of the system.
As soon as the wall is removed, the process called expansion process allows the evacuated chamber to be filled. Work done ΔW = PdV = 0, this is because P the external pressure against which the gas is expanding is zero, therefore the work done is zero.
ΔU which is highly dependent on the temperature is zero since there is no heat transferred in or out of the container due to it being insulated. This therefore means that the initial temperature is the same as the final temperature when the container if filled completely.
T₁ = Final temperature = 310 K
The final Temperature is therefore 310K
Answer:Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). ... You probably have an intuitive feeling for density in the materials you use often. For example, sponges are low in density; they have a low mass per unit volume.

Answer:
3.185 x 10^-3 cm/s
Explanation:
dV / dt = 4 cubic cm per second
r = 10 cm
The volume of sphere is given by
V = 4/3 x π x r³
Differentiate both sides with respect to t
dV / dt = 4/3 x π x 3r² x dr/dt
Put dV / dt = 4 cubic cm per second, r = 10 cm
4 = 4/3 x 3.14 x 3 x 10 x 10 x dr/dt
dr/dt = 3.185 x 10^-3 cm/s
Answer:
Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
