A constant-volume perfect gas thermometer indicates a pressure of 6.69 kPa at the triple point temperature of water (273.16 K).
mina [271]

Answer:

(a) ΔP=0.0245 kPa

(b) P=9.14 kPa

(c)ΔP=0.0245 kPa

Explanation:

(a) As it is perfect gas we can use

(P₁V₁)/T₁=(P₂V₂)/T₂

Since this constant volume so

P₁/T₁=P₂/T₂

T₂ is change in temperature

T₂=1.00+273.16

T₂=274.16 K

P_{2}=(\frac{6.69}{273.16} )*274.16\\P_{2}=6.71449 kPa

ΔP=6.71449-6.69

ΔP=0.0245 kPa

(b) As

P_{2}=(\frac{6.69}{273.16} )*373.16\\P_{2}=9.14 kPa

(c) Same steps as in part (a)

P_{2}=(\frac{9.14}{373.16} )*374.16\\P_{2}=9.164kPa

ΔP=9.164-9.14

ΔP=0.0245kPa

How would seasons on earth be different if the earth was not tilted on its axis
MakcuM [25]

If the Earth's axis were 'straight' ... pefectly perpendicular to the ecliptic
plane ... then:

-- Day and night would be the same length ... every day of the year,
everywhere on Earth !

-- There wouldn't be any seasons, anywhere.  There might still be some
'weather' ... cloudy days, sunny days, occasional rain, wind etc.  But
there would be no average change during the year.  No hot months or
cold months.  In any one place, the weather would always be generally
the same, every day, all year.  Everywhere all around the equator would be
generally the hottest on Earth, and the local climates would generally get
cooler as you moved away from the equator and toward the poles.

Brandy has built a computer model of a weather system. She has included information about bodies of water, the Sun, and the atmo
Mashcka [7]

Answer:

City A will have a higher temperature overall than City B (D)

Explanation:

If all factors other than elevation are the same for both cities, then City A will have a higher temperature overall than City B. This is because there are fewer air molecules at higher elevations. Fewer air molecules mean less heat is absorbed by the atmosphere, and temperatures are lower. This is why areas high in the mountains are often much cooler than areas down on the plains.
