Energy released from changing the phase of a
substance from the liquid phase to solid phase can be calculated by using the
latent heat of fusion. The heat of fusion of iron is calculated as follows:
<span>Energy = mL(f)</span>
<span>9840 cal (4184 J / 1 cal) = .200 kg x L(f)</span>
L(f) = 2.06 x10^8 J/kg
Answer:
Yes.
Explanation:
Substances are made up of matter or matter are made up of tiny molecules or atoms that occur naturally or some are synthetic or man made.
All matter are made up of substances called elements and each elements have its own physical and chemical properties and cannot be broken easily by ordinary chemical reactions.
Of all the 118 elements only 92 occur naturally and 26 are man made or synthetic which are made in the laboratories.
Carbon: 12.01
Neon: 20.18
Iron:55.85
Uranium: 238.03
Answer:
P(total) = 3360 psi
Explanation:
According to the Dalton law of partial pressure:
The pressure of gas is sum of the partial pressure of each components.
P(total) = P₁ + P₂ + P₃ +.... + Pₙ
Given data:
Partial pressure of CO = 2235 psi
Partial pressure of CO₂ = 1125 psi
Total pressure = ?
Solution:
P(total) = P(CO) + P (CO)
P(total) = 2235 psi + 1125 psi
P(total) = 3360 psi
Answer:
air (N2 mixed with O2 and CO2)
Explanation:
It's a mixture of different gases.
