At a temperature of -25 °C, a sample of gas in a rigid container exerts a pressure of 55.8 kPa. At what temperature will the pre

never [62]

<h3>Given:</h3>

$P_{1} = \text{55.8 kPa}$

$T_{1} = -25^{\circ}\text{C + 273 = 248 K}$

$P_{2} = \text{145 kPa}$

<h3>Unknown:</h3>

$T_{2}$

<h3>Solution:</h3>

$\dfrac{P_{1}}{T_{1}} = \dfrac{P_{2}}{T_{2}}$

$T_{2} = T_{1} \times \dfrac{P_{2}}{P_{1}}$

$T_{2} = \text{248 K} \times \dfrac{\text{145 kPa}}{\text{55.8 kPa}}$

$\boxed{T_{2} = \text{644 K}}$

vovikov84 [41]

Answer:

Explanation:

Precision relates to instruments of measurement or scale . A scale measuring upto cm is less precise than an instrument measuring upto mm .

Here the first measurement appears to have been taken with an instrument measuring up to metre and the second measurement appears to have been taken with an instrument measuring up to decimeter . So second measurement is most precise .

Third measurement is closest to the actual measurement that is 45.0 m , so it is most accurate measurement .
