Given that 242.2J of energy is required to heat 81.6g of copper from 27.5°C to 35.2°C, find the specific heat of copper.
nikdorinn [45]

Answer:

c = 0.39 J/g.°C

Explanation:

Given data:

Energy required = 242.2 J

Mass of copper = 81.6 g

Initial temperature = 27.5°C

Final temperature = 35.2°C

Specific heat capacity of copper = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 35.2°C -  27.5°C

ΔT = 7.7°C

242.2 J = 81.6 g ×c ×  7.7°C

242.2 J / 81.6 g = c ×  7.7°C

c = 3 J/7.7g.°C

c = 0.39 J/g.°C

Raw materials used in the manufacturing of indigenous soap
Harrizon [31]

Answer:

Fat

Alkali

Explanation:

Fat and alkali are the two primary raw materials needed to manufacture soap.

Sodium hydroxide or potassium hydroxide is generally used as an alkali. The use of alkali depends on the intended application of the soap.

Raw animal fat was used in the past but these days, processed fat is used in the soap manufacturing process. Vegetable fats ( e.g, palm oil, olive oil, coconut oil) are also being used in soap manufacturing.

Additives are also used to enrich the color and texture of the soap.
