Explanation:

Sensible heat is defined as the heat exchanged by a system that results in change in temperature of the system without changing volume or pressure of the system.

Latent heat is the heat absorbed or released during phase conversion of a substance. It is also called as hidden heat as it does not result into change in temperature of the system and is only used to break the inter molecular forces between particles.

Heat capacity is the quantity of heat required to raise the temperature of a substance by one degree Celsius.

D. 62.8 cm

Explanation:

Since the radius of each jar lid is 5 centimeters. The total length of ribbon that's needed for each jar lids will be:

= 2πr = 2 × 3.14 × 5 = 31.4

Therefore, the total length of ribbon that she will need for the two jar lids will be gotten by multiplying 2 by 31.4cm. This will be:

= 2 × 31.4

= 62.8 cm
