The answer is 4567 grams of ice in the five pound bag to specific heat is the -20 degrees! Hope I helped! :)
Answer:
Specific heat capacity
Explanation:
Heat capacity is defined as amount of the heat supplied or absorbed by the given mass of the material so to make a unit change in the material's temperature.
The SI unit is Joule / kelvin (J/K).
It is an extensive property.
While,
<u>Specific heat capacity is the amount of heat absorbed or lost by one gram of mass of the substance to raise it's temperature by 1°C or 1 K
</u>
<u>It is an intensive property. </u>
Answer:
+3
Explanation:
-10 + 13 = +3
-10 IS THE NUMBER OF ELECTRONS
13 IS THE NUMBER OF PROTONS
Answer:
7.71 atm
Explanation:
Given the following data:
According to the ideal gas law, we know that the product between pressure and volume of a gas is equal to the product between moles, the ideal gas law constant and the absolute temperature:
Since the temperature and the ideal gas constant are constants, as well as the fixed container volume of 5 L, we may rearrange the equation as:
This means for two conditions, we'd obtain:
Given:
Solve for the final pressure:
Now, according to the Dalton's law of partial pressures, the partial pressure is equal to the total pressure multiplied by the mole fraction of a component:
Knowing that:
And:
The equation becomes:
Substituting the variables:
