When 6.85×10⁵ cal is converted to kilojoules, the result obtained is 2866.04 KJ

<h3>Data obtained from the question </h3>
  • Energy (cal) = 6.85×10⁵ cal
  • Energy (KJ) =?

<h3>Conversion scale </h3>

1 cal = 0.004184 KJ

<h3>How to convert 6.85×10⁵ cal to kilojoules</h3>

1 cal = 0.004184 KJ

Therefore,

6.85×10⁵ cal = 6.85×10⁵ × 0.004184

6.85×10⁵ cal = 2866.04 KJ

Thus, 6.85×10⁵ cal is equivalent to 2866.04 KJ

A compressor takes 0.50 m3 of a gas at 33°C and 760 mmHg and compresses it to 0.10 m3, cooling it to -55°C at the same time. Wha
vodomira [7]

Answer is C.

Converting temperatures to degrees K: 33 degrees C = 306 K and -55 = 218 degrees K.

By the ideal gas law:-

760 * 0.50 / 306  = P * 0.10 / 218    

P =  760 * 0.50 * 218 / 306 * 0.10

= 2700 mm Hg  answer
