Mrs. Franklin decides to use her new aluminum pan to scramble eggs. She wants to determine how much heat energy will be needed to heat her aluminum pan from 20 degrees celsius to 220 degrees celsius. She obtains the specific heat of aluminum from the reference
table. It lists the specific heat of aluminum as 0.90 N/kg*degrees celsius. The pan has a mass of 0.5 kg. She does the calculation
correctly. Which one of the following is her answer?
Your
0.45 joules of heat energy
O 0.9 kilojoules of heat energy
O 90 kilojoules of heat energy
180 joules of heat energy

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
