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 half-life of Material 1 and Material 2 are equal.
Explanation:
Material 1 disintegrates to half its mass three times in 21.6 s, to go from 100g
to 12.5g. That is,
100g - 50g - 25g - 12.5g
Material 2 disintegrates to half its mass three times in 21.6 s, to go from 200g to 25g. That is,
200g - 50g - 25g - 12.5g.
This means that regardless of their initial masses involved, material 1 and material 2 have equal half-life.
Their half-life is 21.6 ÷ 3 = 7.2 sec

Answer:
Explanation:
For amount of radiation from a hot body there is Stefan's Boltzman's law which is given below .
E = e σ T⁴
E is amount emitted , e is emissivity , σ is stefan's constant = 5.67 X 10⁻⁸ W / m² . for earth e =.85 approx
E = .85 x 5.67 X 10⁻⁸ x T⁴
604 = .85 x 5.67 X 10⁻⁸ x T⁴
604 = 4.82 x 10⁻⁸ T⁴
T⁴ = 125.31 x 10⁸
T = 3.3457 x 10²
= 334.57K
Temperature in Celsius = 334.57 - 273
= 61.57 Celsius .
Answer: An unhealthy diet can increase the risk of some cancers. Overweight and obesity are associated with at least 13 types of cancer, including endometrial (uterine) cancer, breast cancer in postmenopausal women, and colorectal cancer. These cancers make up 40% of all cancers diagnosed.
