Answer: The heat moves through the atmosphere through the process of radiation.
Explanation:
There are three modes of transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
3. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards.
Thus heat moves through the atmosphere through the process of radiation
Answer:
Fungi are a food source for animals and humans. This point do not apply on fungi.
Explanation:
Roles of fungi:
Penicillin and Cephalosporins are the antibiotics made by fungi. They are natural sources of antibiotics.
Fungi are eaten by animals examples are mushroom, agaricus and some animals even eat poisonous mushrooms.
Fungi destroy by releasing chemicals into the rock and they get iron this way and then deeply burrow the rocks and harming them.
Fungi acts as a decomposer to nourish the soil and improves vegetation.
Many infections are caused by fungus like ringworm infection, candida and Athlete's food are some examples.
To perform nuclear fusion reactions, the following requirements must be present: Get a very high temperature to separate the electron from the nucleus, approaching this another beating electrostatic repulsion forces. The gaseous mass consisting in the electrons and free atoms is called highly ionised plasma.
So, it’s chemical plasma.
Hope this helps:)

Answer:
2.94g/L
Explanation:
First, let us derive an expression for the density, using the ideal gas equation:
PV = nRT (1)
V = nRT/ P (2)
Recall:
Number of mole(n) = mass(m)/Molar Mass (M)
n = m/M
Substituting the value of n into equation 2:
V = nRT/ P
V = mRT/ MP
Now Divide both side by m
V/m = RT/ MP
Inverting the above equation, we have:
m/V = MP/RT
But Density = m/V
Density = MP/RT
From the question given, we obtained the following data:
P = 2.3atm
T = 305K
Molar Mass of O2 = 16x2 = 32g/mol
R = 0.082atm.L/K /mol
Density = (32x2.3)/(0.082x305)
Density = 2.94g/L
