Real gases may be expected to deviate from Charles' Law at pressures near the temperature.

1 answer:

7 0

<span>Real gases deviate from ideal gases when there are conditions such as low temperature and high pressures. Charles' law holds the pressure constant with varying temperature. Given that there is constant pressure, low temperatures cause the deviation from the state of ideality. </span>

What element has 47 protons in its nucleus?

sesenic [268]

Answer:

b). silver (Ag)

Explanation:

If you look at the periodic table, you just need to look at the atomic number of the element, because the atomic number tells you how many protons there are in the nucleus of the element.

But do be careful because some periodic tables have the molar mass at the top left corner, but the one I use has the atomic number at the top left corner, so make sure you look for the atomic number and not the molar mass.

What does vinegar do to eggs

andre [41]

Eggshells are made primarily of calcium carbonate. The acid in vinegar softens the calcium of the eggshell. Adding a little vinegar to the water when boiling eggs is an old cook’s trick that makes them easier to peel.

is the approximate relation celsius = 1/2 fahrenheit a better approximation at higher or lower temperatures?

kirill115 [55]

Answer : The approximate relation Celsius = 1/2 Fahrenheit is a better approximation at higher temperatures

Explanation :

The formula for Celsius to Fahrenheit conversion is

$C = (F-32) \times \frac{5}{9}$

At lower temperature the value that needs to be subtracted (32) is large enough as a result the approximation "celsius = 1/2 fahrenheit " does not seem valid.

For example, 50 F is 10°C.

$(50 - 32) \times \frac{5}{9} = 10 C$

This is almost 1/5 of Fahrenheit temperature.

But at higher temperatures , the value becomes insignificant and also the ratio 5/9 tend to be equal to 0.5.

For example, 2000 F is 1093°C

$(2000 - 32) \times \frac{5}{9} = 1093 C$

This is almost half of Fahrenheit temperature.

Therefore , the approximate relation Celsius = 1/2 Fahrenheit is a better approximation at higher temperatures
