Lattice energy is the amount of energy expelled when the solid is disintegrated into ions. For example, the solid is Sodium Chloride. In ionic form, that would consist of sodium and chlorine ions.The solid with a smaller lattice energy would be easily disrupted, hence, when a solvent is incorporated, the solid becomes solvated ions.
Answer:
a.) because your ankle is taking in cold energy from the cold pack
Explanation:
all of the other ones say heat, which is not applied in this question
Answer:
36.2 K
Explanation:
Step 1: Given data
- Initial pressure of the gas (P₁): 8.6 atm
- Initial temperature of the gas (T₁): 38°C
- Final pressure of the gas (P₂): 1.0 atm (standard pressure)
- Final temperature of the gas (T₂): ?
Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K
The alcohol has an oxygen atom single-bonded to hydrogen and single-bonded to a carbon-containing group.
<h3>What is alcohol? </h3>
Alcohol is defined as the organic compound which is derived from an hydrocarbon by replacing one hydrogen by hydroxyl group(—OH).
The general formula of alcohol is ROH.
where, R is the alkyl group.
The first member of alcohol is ethanol.
<h3>Physical properties of alcohol</h3>
- Alcohols are colourless.
- They give a sweet smell except for glycerol and few lower alcohols.
- They are flammable and produce a blue flame on burning.
- They don't produce any kind of smoke while burning.
- Alcohol are liquid at room temperature.
Thus, alcohol is an organic compound which contain an oxygen atom which is single-bonded to hydrogen and single-bonded to a carbon-containing group.
