Answer:
V
Explanation:
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.
Answer:
19.39 mL.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have different values of V and T:
<em>(V₁T₂) = (V₂T₁)</em>
<em></em>
V₁ = 22.8 mL, T₁ = 48°C + 273 = 321 K,
V₂ = ??? mL, T₂ = 273 (standard temperature = 273 K),
- Applying in the above equation
<em>(V₁T₂) = (V₂T₁)</em>
<em />
∴ V₂ = (V₁T₂)/(T₁) = (22.8 mL)(273 K)/(321 K) = 19.39 mL.
The people of he world believe and they don't believe.
I,myself, think we do land don't live in multiverse.
Why: Because in science I hear that there are many universes out there that need to b explored.
Not: Because if we did, don't you think that Astronauts and the U.S. would try and find different universes.
I hope I helped you!:)
Answer:
waste energy = 30 J
Explanation:
Given that.
Input energy = 100 J
Useful energy = 70 J
We need to find the amount of waste energy.
Waste energy = total energy - used energy
= 100 J - 70 J
= 30 J
Hence, 30 J of energy is waste energy.
Answer:
The process in which a solid transforms into a liquid is called melting. This happens when the solid is so hot that it melts.
