One way to measure temperature in some applications is to monitor the gas pressure in a rigid, closed container. What is the tem

julia-pushkina [17]

Answer:

296.43 K is the temperature of a vessel when pressure reads 1.250 atm.

Explanation:

At STP, when pressure is 1.000 atm the value of temperature is 273,15 K.

If the pressure at temperature T reads as 1.250 atm.

$P_1=1.000 atm, T_1=298.15K$

$P_2=1.250 atm,T_2=?$

Applying Gay Lussac's law:

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$ (At constant volume)

$\frac{1.000 atm}{273.15 K}=\frac{1.250 atm}{T_2}$

$T_2=296.43 K$

296.43 K is the temperature of a vessel when pressure reads 1.250 atm.

In pea plants, yellow seeds are dominant to green seeds. A heterozygous yellow-

san4es73 [151]

Answer:

The phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours

Explanation:

The crossing to determine the offsprings is shown in the image attached where we have two green (Yy) seeds and two yellow (yy) seeds as offsprings.

Thus, <u>the phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours</u>.

Note, the dominant allele is "Y" while the recessive allele is "y". Thus, Yy would produce a yellow colour while yy would produce a green colour (as both mentioned in the question).

Also note that phenotype describes the outward properties/characteristics of an individual.

What types of elements- metals,

crimeas [40]

Answer:

Noble gases

Explanation:

The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.

The reason for this difficult is that their electronic configuration confers a stable configuration them.

The ionization energy is the energy required to remove the most loosely held electrons in an atom.
Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.
