Answer:
Option C. 760mmHg & 0°C
Explanation:
The standard pressure = 760mmHg = 1atm = 760torr = 101325N/m2
= 101325Pa
Standard temperature = 0°C =273K
From the above, the right combination is 760mmHg and 0°C
Na, Ba, Cs and Ni are metals.

The term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.
<h3>
What is specific heat capacity?</h3>
Specific heat capacity is the quantity of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius. The unit of specific heat capacity is joule per gram per degree Celsius (J/g⁰C).
<h3>Difference between
heat capacity and
specific heat capacity</h3>
Specific heat capacity is heat required to raise the temperature of a unit mass of a substance while heat capacity is the quantity of heat required to raise the temperature an entire mass of a substance.
Heat capacity is measure in Joules (J) while specific heat capacity is measured in joule per gram per degree Celsius (J/g⁰C).
Thus, the term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.

Answer:
Explanation: Ethanol, CH3CH2OH, has the highest of the three boiling points because it has the strongest dipole–dipole forces between molecules due to hydrogen bonding. ... Dimethyl ether, CH3OCH3, has the second- highest boiling point because it has dipole–dipole forces between molecules.
