Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
Explanation:
Hi there!
We can use the equation:
d = x₀ + vt, where:
x₀ = initial distance from the reference point
v = velocity (m/s)
t = time (sec)
Plug in the given values:
d = 248 + 5(49)
d = 493m
Hi , basically the atmosphere is made up of 78% of nitrogen, nitrogen is very special and important because if the air was just made up of oxygen the air that we breath would be very flammable and toxic .That's why we have nitrogen.
Answer:
16
Explanation:
If we treat the pot as a black body, then:
q = σ T⁴ A,
where q is the heat per second radiated,
σ is the Stefan-Boltzmann Constant,
T is the absolute temperature,
and A is the surface area.
If the absolute temperature doubles, then q increases by a factor of 2⁴ = 16.
