Answer:
The answer to your question is 0.62 atm = 62.82 kPa = 471.2 mmHg
Explanation:
Data
P = 0.62 atm
P = ? kPa
P = ? mmHg
Process
1.- Look for the conversion factor of atm to kPa and mmHg
1 atm = 101.325 kPa
1 atm = 760 mmHg
2.- Do the conversions
1 atm ----------------- 101.325 kPa
0.62 atm ------------ x
x = (0,62 x 101.325) / 1
x = 62.82 kPa
1 atm ------------------ 760 mmHg
0.62 atm ------------ x
x = (0.62 x 760)/1
x = 471.2 mmHg
Answer:
Free Energy (G) can either increase or decrease for a reaction when the temperature increases. It depends on the entropy (S) change. The change in a quantity is represented by the Greek letter delta. ... Hence, when the temperature increases the numeric value of the free energy becomes larger.
Explanation:
Barrier island refers to the large sandbars along the coastline that form
from deposition of sand over long period of time.
<h3>Features of a Sandy environment </h3>
The features of a sandy environment include the following:
Barrier Island are formed when sand is deposited over a long time and this
helps to prevent erosion along the coastline area.

Answer:
The energy required is 3225 Joules.
Explanation:
Given,
mass of lead cube = 500 grams
T₁ = 25°C
T₂ = 75°C
specific heat of lead = 0.129 J/g°C
Energy required to heat the lead can be found by using the formula,
Q = (mass) (ΔT) (Cp)
Here, ΔT = T₂ - T₁ = 75 - 25 = 50
Substituting the values,
Q = (500)(50)(0.129)
Q = 3225 Joules.
Therefore, energy required is 3225 J.
