When you transferred the hot metal from the boiling water and into the calorimeter, The effect will be
- Change in temp is positive
- Temp of metal V, dT=-ve
- No change occurs in the specific heat of metal
This is further explained below.
<h3>What is the Specific heat of the metal?</h3>
a )Since the metal of the cup is hot and the water inside is cold, the water's temperature will rise as heat is transferred from the metal to the liquid.
Change in temp is positive
b)
Due to (a), heat is lost from the food to the water in the cup, lowering the metal's temperature.
Temp of metal V, dT=-ve
c)
No change occurs in the specific heat of metal because of its constant property.

Answer:
hydrogen ions
Explanation:
because acid is the specie that have ability to donate proton or forming bond with electron pair
Answer:
The total pressure will be 1, 021 atm
Explanation:
We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:
760mmHg----1 atm
542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm
234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm
Pt=P Ne + P At= 0,713 atm + 0,308 atm= <em>1, 021 atm</em>
