The capability to do work is said to be energy. It can neither be created nor be destroyed according to law of conservation of energy. Energy exist in different forms depends upon the work to be done such as potential energy, kinetic energy, mechanical energy, heat energy etc.

Now, when the guitarist plucks the guitar strings to make sound, he uses mechanical energy and when guitarist plucks the guitar strings guitar produces sound energy also.

Thus, option (d) is the correct answer.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚C inside a freezer for a night. When he took it out, its new volu
katrin2010 [14]

Answer:

T2=276K

Explanation:

Given:

Initial volume of the balloon V1 = 348 mL

Initial temperature of the balloon T1 = 255C

Final volume of the balloon V2 = 322 mL

Final temperature of the balloon T2 =

To calculate T1 in kelvin

T1= 25+273=298K

Based on Charles law, which states that the volume of a given mass of a ideal gas is directly proportional to the temperature provided that the pressure is constant. It can be applied using the below formula

(V1/T1)=(V2/T2)

T2=( V2*T1)/V1

T2=(322*298)/348

T2=276K

Hence, the temperature of the freezer is 276 K

Which of the following matches is not correct?
Furkat [3]

Answer:

SO42 - Trigonal planar ion

Explanation:

The SO4^2- ion is tetrahedral and not trigonal planar because the sulphur atom has four regions of electron density which includes the lone pair of electrons on sulphur atom.

This accounts for the observed tetrahedral arrangement of electron pairs around the central sulphur atom in SO4^2- ion, hence the answer.
