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:
the answer is Z b/c wehave to forces and they have different direction. then search the sum of the forces. thus we gain 40 N to right.
Calcium belongs to the alkaline earth metal group. Within a group, the melting point decreases from top to bottom. This is because the as the atomic radii increases the outer valence electrons are shielded by the inner electrons and experience a lower nuclear attraction. As a result the bonds can be broken easily which lowers their melting point.
The three elements below Calcium ib Group II A which have a lower melting point are: Strontium (Sr), Barium (Ba) and Radium (Ra)
