Answer:
Precision is determined by a statistical method called a standard deviation To determine if a value is precise find the average of your data, then subtract each measurement from it
Answer: mutation
explanation: no other species of its kind will have this mutation
climate change is a change in climate in the Earth 's normal weather patterns for different climates. it normally changes little by little over the years.the earth is cooler and warming .now it's getting warmer. this phenomenon is also known by as globall warming.it's causes are:
1.energy uses
2.agriculture and land use 3.Transport 4.Industries 5.Growing demands for food and water
A greenhouses is made from glass or clear plastic. It is useful for growing plants in winter in cooler climates.

Explanation:
Answer:
Radiation
Explanation:
Radiation refers to the emission of energy in rays or waves
Answer:
H vaporization = 100.0788 kJ/mol
Explanation:
Use clausius clapyron's adaptation for the calculation of Hvap as:
Where,
P₂ and P₁ are the pressure at Temperature T₂ and T₁ respectively.
R is the gas constant.
T₂ = 823°C
T₁ = 633°C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So, the temperature,
T₂ = (823 + 273.15) K = 1096.15 K
T₁ = (633 + 273.15) K = 906.15 K
P₂ = 400.0 torr , P₁ = 40.0 torr
R = 8.314 J/K.mol
Applying in the formula to calculate heat of vaporization as:
Solving for heat of vaporization, we get:
H vaporization = 100078.823 J/mol
Also, 1 J = 10⁻³ kJ
So,
<u>H vaporization = 100.0788 kJ/mol</u>
