Physical change

Any change to the physical properties of a substance is called a physical change.

Physical changes are usually reversible as no new substance is formed. It is the same substance but with changed physical properties.

Chemical change

A change in which one or more new substances are formed is called as a chemical change.

Usually a chemical change involves a chemical reaction, which forms new products.

A machine require 2,000 joules to raise a 20 kilogram block a distance of 6 meters. How efficient is the machine?
Nataly_w [17]
Potential energy = (mass) x (gravity) x (height) .

To raise the 20kg block 6 meters, you need to give it

                         (20 kg) x (9.8 m/s²) x (6 m) = 1,176 joules

of potential energy.

Your machine takes 2,000 joules of energy to give the block
the 1,176 joules that it takes.

Your machine is only  (1176 / 2000) = 58.8% efficient .

The other 'missing' 824 joules of energy doesn't just disappear.
It heats the machine, and the air around it.  The final result is
that when you use that machine to lift blocks, you have to use
even MORE energy, to blow cool air on the machine and prevent
it from overheating and breaking.

Alenkinab [10]

Asymptomatic bacteruria is when there are elevated bacteria levels in urinalysis or there is culture growth but there are no symptoms thereby asymptomatic. Although asymptomatic, asymptomatic bacteruria is a form of urinary tract infections but only needs to be treated if the urinary tract infection is symptomatic or complicated such that in pregnancy, those with unstable comorbidities such as diabetes, and those with structural anatomic urinary tract defect i.e. vesicoureteral reflux. 


The correct answers are:

(1) Physical findings are absent; (2) asymptomatic; (2) if no symptoms present, no antibiotics recommended; (4) elevated bacteria level in urinalysis and culture
