The answer is- The energy of 1 L water at temperature 347.78 °C have more energy as 1 L of water at temperature 65°C.
Heat is a type of energy that causes a person's body to feel hot or cold.
While the temperature of an object is a parameter that indicates how hot or cold the object is.
How is the temperature in degree Fahrenheit converted to degree celsius?
- To convert the temperature in Fahrenheit to Celsius, subtract 32 and multiply by 5/9.
°
- Now, heat is a form of energy that flows from hotter object to colder object and temperature indicates whether the object is hot or cold by measuring its average kinetic energy.
- Now, the given temperature of 1 L water is 658 °F. This temperature in degree celsius is calculated as-
°C
- Now, higher the temperature, higher is the energy of water. Thus, the energy of 1 L water at 347.78 °C have more energy as 1 L of water at 65°C.

Answer:
B. That energy can only be converted between different forms
Explanation:
The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.
Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.
Energy according to the law of conservation of energy is not produced neither is it destroyed.
Energy is simply transformed from one form to another.
Answer:
Explanation:
Formula of percent composition:
% X = ( mass of element in compound / total mass of compound ) × 100
11) Al₂O₃
Al = 27 g/mol
O = 16 g/mol
%Al = (54 / 101.96) × 100
%Al = 52.9%
%O = (48 / 101.96) × 100
%O = 47.1%
12) C₅H₅O₅
C = 12 g/mol
H = 1 g/mol
O = 16 g/mol
C% = (60 / 145 ) × 100
C% =41.4%
H% = (5 / 145 ) × 100
H% =3.4%
O% = (80 / 145 ) × 100
O% = 55.2%
13) BaBr₂
Ba = 137.3 g/mol
Br =79.9 g/mol
Ba% = (137.3 / 297.14) × 100
Ba% = 46.2%
Br% = (159.8/ 297.14) × 100
Br% = 53.8%
14) Fe₃(PO₃)₂
Fe = 55.8 g/mol
P = 31 g/mol
O = 16 g/mol
Fe = (167.4/325.48) × 100
Fe = 51.43%
P = (62/325.48) × 100
P = 19.05%
O = (96 /325.48) × 100
O = 29.49%
