Answer:
This occurs through radiation, convection, conduction, and, if the subject is wet, evaporation. Most commonly, the body temperature decreases, although in more extreme climates an increase in cadaver temperature may result.
Answer:
ΔG° = -8.8 kJ/mol
Explanation:
The standard Gibbs free energy of reaction (ΔG°) can be calculated using the following expression.
ΔG° = ΔH° - T.ΔS°
where,
ΔH°: standard enthalpy of reaction
T: absolute temperature
ΔS°: standard entropy of reaction
At 298 K (the temperature that is usually used), ΔG° for the hydrolysis of lactose is:
ΔG° = ΔH° - T.ΔS°
ΔG° = 0.44 kJ/mol - 298 K × 0.031 kJ/mol.K
ΔG° = -8.8 kJ/mol
The solubility of a given solute in a given solvent typically depends on temperature. Many salts show a large increase in solubility with temperature. ... A few, such as cerium(III) sulfate, become less soluble in water as temperature increases.
Answer:
One molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure.
Explanation:
Hope this helps :) Have a great day!
As the volume of a gas increases <em>at constant temperature</em>, the number of particle impacts per unit area decreases.
There is the same number of impacts, but they are spread over a larger surface area.
Thus, the number of impacts per unit area decreases.
