Answer:

Intake, compression, power, exhaust

Explanation:

To generate power, an engine must continually cycle through the same four stages of operation.

Intake: A mixture of air and fuel is drawn into the cylinder.

Compression: The piston rises and compresses the mixture.

Power: The spark plug ignites the mixture and causes an explosion.

Exhaust: The leftover gases are released from the cylinder.

Answer:

Intake, compression, power, and exhaust

Explanation:

A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

Glacier National Park in Montana is approximately 4,100 ft above sea level with an atmospheric pressure of 681 torr. At what tem

lapo4ka [179]

Answer : The temperature of liquid is, 369.9 K

Explanation :

The Clausius- Clapeyron equation is :

$\ln (\frac{P_2}{P_1})=\frac{\Delta H_{vap}}{R}\times (\frac{1}{T_1}-\frac{1}{T_2})$

where,

$P_1$ = vapor pressure of liquid at 373 K = 681 torr

$P_2$ = vapor pressure of liquid at normal boiling point = 760 torr

$T_1$ = temperature of liquid = ?

$T_2$ = normal boiling point of liquid = 373 K

$\Delta H_{vap}$ = heat of vaporization = 40.7 kJ/mole = 40700 J/mole

R = universal constant = 8.314 J/K.mole

Now put all the given values in the above formula, we get:

$\ln (\frac{760torr}{681torr})=\frac{40700J/mole}{8.314J/K.mole}\times (\frac{1}{T_1}-\frac{1}{373K})$

$T_1=369.907K\approx 369.9K$

Hence, the temperature of liquid is, 369.9 K

what volume of hydrogen gas is evolved from a reaction between 0.52 g of Na and water? This gas is collected at 20 C and 745mmHg

guapka [62]

The volume of hydrogen gas that evolved is calculated as follows
by use of ideal gas equation

that is PV = nRT
P=745 mm hg
V= ?
R(gas constant)= 62.36 L.mm hg/mol.k
T= 20 + 273 = 293 k
n=number of moles which is calculated as follows
find the moles of Na used
= 0.52/23=0.023 moles

write the reacting equation
2Na +2H2O =2NaOH +H2
by use of reacting ratio between Na : H2 which is 2:1 therefore the mole of H2 = 0.023/2 =0.0115 moles

by making the volume the subject of the formula
v=nRT/P
V= (0.0115 x 62.36 x 293) / 745 = 0.283 L

If snails and crayfish die, what happens to the other species?

elixir [45]

Crayfish are very intolerant of pollution and other human-generated fouling of their environment. ... This abundance may be due more to the acid-generated absence of fish which prey on crayfish than to a direct, positive influence of the acid on the crayfish itself.
