Which metal has the highest specific heat capacity

Lithium is the metal that has the highest specific heat capacity.

What is the definition of specific heat

The heat needed to raise the temperature of 1 g of a substance 1° C - apex

Why does temperature stay constant during a phase change

To put it in simple terms, all of the energy that would normally increase the temperature of the object, is being used to convert the object from one phase to another.

Once the object has completely changed to the new phase, the energy is not needed for phase change and raises the temperature of the object.

Because energy is being used to overcome intermolecular forces(apex)

What does the difference in potential energy between the reactants and products represent

It represents the change in enthalpy for the reaction.

What does the field of thermodynamics relate to

Changes in energy in systems

What does S0 mean

the system has become more random

Which of the following reactions shows h formation of CO2 releases 393.5 kjmol

C(s)+O2(g) yields CO2(g)+393.5kJ

What statements about airplane and rocket flight is true

Only one requires air molecules to generate lift.

How is the H fusion used to calculate the mass of solid that 1kJ of energy will melt
