A 250. mL sample of gas at 1.00 atm and 20.0°C has the temperature increased to 40.0°C and the volume increased to 500. mL. What

ladessa [460]

Answer:

New pressure is 0.534 atm

Explanation:

Given:

Initial volume of the gas, V₁ = 250 mL

Initial pressure of the gas, P₁ = 1.00 atm

Initial temperature of the gas, T₁ = 20° C = 293 K

Final volume of the gas, V₂ = 500 mL

Final pressure of the gas = P₂

Final temperature of the gas, T₁ = 40° C = 313 K

now,

we know for a gas

PV = nRT

where,

n is the moles

R is the ideal gas constant

also, for a constant gas

we have

(P₁V₁/T₁) = (P₂V₂/T₂)

on substituting the values in the above equation, we get

(1.00 × 250)/293 = (P₂ × 500)/313

P₂ = 0.534 atm

Hence, the <u>new pressure is 0.534 atm</u>

How much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m^2 exerts a pres

andriy [413]

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

$F=P\times A\\\\F=5\times 25\\F=125\ N$

So, the weight of the man is 125 N.

sladkih [1.3K]

Answer:

Gastric juice is an acidic substance ( Strongly acidic)

Explanation:

According to the table shown in the question:

Gastric juice turns blue litmus paper to red
It is neutral to red litmus

Note: Any substance that turns blue litmus paper red and is neutral to red litmus paper is an acidic substance.

Moreover, gastric juice is a combination of Pepsin and HCl and it has a PH that varies between 1 and 3. This PH is typical of a strongly acidic substance.
