Answer:

Explanation:

Inferences are not based on anything from the text while guesses are made only using the text. Inferences are based on evidence in the text while guesses are not. Inferences are made by only using major details from the text while guesses only use minor details.

At 35.0°c and 3.00 atm pressure, a gas has a volume of 1.40 l. what pressure does the gas have at 0.00°c and a volume of 0.950 l

Leona [35]

Answer : The pressure of gas will be, 3.918 atm and the combined gas law is used for this problem.

Solution :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 3 atm

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas = 1.40 L

$V_2$ = final volume of gas = 0.950 L

$T_1$ = initial temperature of gas = $35^oC=273+35=308K$

$T_2$ = final temperature of gas = $0^oC=273+0=273K$

Now put all the given values in the above equation, we get the final pressure of gas.

$\frac{3atm\times 1.40L}{308K}=\frac{P_2\times 0.950L}{273K}$

$P_2=3.918atm$

Therefore, the pressure of gas will be, 3.918 atm and the combined gas law is used for this problem.

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table. A 2

svp [43]

Answer:

The correct option is;

X, W, Y, Z

Explanation:

The parameters given are;

Spring (S), Spring Constant (N/m)

W, 24

X, 35

Y, 22

Z, 15

The equation for elastic potential energy, $E_e$ , is $E_e = 0.5 \times k \times x^2$

The above equation can also be written as $E_e =\dfrac{1}{2} \times k \times x^2$

Where:

k = The spring constant in (N/m)

x = The spring extension

Therefore, since the elastic potential energy, $E_e$ , of the spring is directly proportional to the spring constant, k, we have the springs with higher spring constant will have higher elastic potential energy, $E_e$ , therefore the correct order is as follows;

X > W > Y > Z

HeeeeeeeeeeeelllllllllllllllllllllllpppppppppppppppppppppppppppppFind the statement about Fusion that is false.

Pie

Fusion releases less energy than fission

fusion most commonly combines heavy isotopes of hydrogen into helium.

Explanation:

Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.

The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.

Nuclear fusion reactions in the core of stars powers the universe.
The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
Small nuclei are involved in nuclear fusion and not the large ones.
Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.
