Passenger airplanes take off in the troposphere but can eventually move into

1 answer:

5 0

Well that is because the stratosphere has lower temperatures and low air density. This gives the airplane less air pressure and with low air density they can fly faster :) Hope this helps.

Answer:

The complete aerobic oxidation of glucose is coupled to the synthesis of as many as 36 molecules of ATP

Explanation:

Glycolysis, the initial stage of glucose metabolism, takes place in the cytosol and does not involve molecular O2. It produces a small amount of ATP and the three-carbon compound pyruvate. In aerobic cells, pyruvate formed in glycolysis is transported into the mitochondria, where it is oxidized by O2 to CO2. Via chemiosmotic coupling, the oxidation of pyruvate in the mitochondria generates the bulk of the ATP produced during the conversion of glucose to CO2. The biochemical pathways that oxidize glucose and fatty acids to CO2 and H2O.

cual es el calor especifico de una sustancia cuya masa es de 7 gramos, si absorbe 180 calorias para pasar de 10 grados celsius a

VladimirAG [237]

What is the specific heat of a substance whose mass is 7 grams, if it absorbs 180 calories to go from 10 degrees Celsius to 85 degrees Celsius

Answer:

0.343cal/g°C

Explanation:

Given parameters:

Mass of substance = 7g

Quantity of heat absorbed = 180calories

Initial temperature = 10°C

Final temperature = 85°C

Unknown:

Specific heat of the substance = ?

Solution:

To solve this problem, the specific heat of a substance is the amount of heat needed to raise the temperature of a unit mass of that substance by 1°C.

Mathematically;

C = $\frac{Q}{m (T_{2} - T_{1} )}$

C is the specific heat

Q is the amount of heat

m is the mass

T is the temperature

1 and 2 are the initial and final states

Now, insert the parameters and solve;

C = $\frac{180}{7 (85 - 10)}$ = 0.343cal/g°C
