in a container filled with gas at a constant temperature, the volume is 183 mL and the pressure is at 310 mm Hg. The desired new volume is 90.0 mL. What is the required new pressure? 53 mm Hg 150 mm Hg 330 mm Hg 630 mm Hg

Answers

Answer 1

Answer:

Answer:

630 mmHg is the required new pressure.

Explanation:

At constant temperature;

Initial volume of the gas, $V_1 = 183 mL$

Initial pressure exerted by the gas, $P_1= 310 mmHg$

Final volume of the gas , $V_2= 90.0 mL$

Final pressure exerted by the gas , $P_2=?$

At constant temperature pressure and volume of the gas varies indirectly.

$P_1V_1=P_2V_2$ (Boyle's Law)

$P_2=(310 mmHg* 183 mL)/(90.0 mL)=630.33 mmhg\approx 630 mmHg$

630 mmHg is the required new pressure.

A moving hang glider has ____ energy, which converts to _____ energy once the hang glider stops.

Answers

A moving hang glider has kinetic energy, which converts to potential energy once the hang glider stops.

Answer: kinetic , potential

Explanation: According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only be transformed from one form to another.

Kinetic energy is the energy possessed by an object by virtue of its motion.

Potential energy is the energy possessed by an object by virtue of its position.

Thus a moving hang glider possesses kinetic energy which is converted to potential energy when it stops.

Feather color in budgies is determined by two different genes Y and B. YYBB, YyBB, or YYBb is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white. Two blue budgies were crossed. Over the years, they produced 22 offspring, 5 of which were white. What are the most likely genotypes for the two blue budgies?

Answers

Answer:

The most likely genotypes for the two blue budgies would be yyBb

Explanation:

There are three options to cross two blue parakeets:

yyBB x yyBB

yyBB x yyBb

yyBb x yyBb

of the first option, the F1 genotypes will be 100% yyBB (blue)

In the second option, the F1 budgies will be yyBB or yyBb (blue in both cases). In contrast, in the third option, the F1 genotypes will be yyBB, yyBb (blue in both cases) and yybb (white).

Name two organelles you could find in a euglena that you couldn't find in a zooflagellate

Answers

Zooflagellate is a free living protozoan with a whip like appendage. It is non-photosynthetic and feed on decaying organic matter. Euglena is a single cell flagellate eurkaryote, which has features of both plant and animal. Two organelles that are present in euglena but which are not present in zooflagellate are chloroplast and photoreceptors.
