When a stationary mass of gas was
compressed without friction at
constant pressure its initial state of
0.8 m3 and 0.105 MPa was found to
change to final state of 0.40 m3 and
0.105 MPa. There was a transfer of 85
kJ of heat from the gas during the
process.How much did the internal
energy of the gas change ? *

While a unit expresses a specific type of physical quantity, a dimension assigns a property of scale so that the unit can be measured. Temperature at which water has the highest density is usually taken as 4°C(39.2°F). The continuum concept in hydraulics assumes that a fluid often behaves as if itwere comprised of continuous matter that is infinitely divisible into smaller and smaller parts.arrow_forwardk = 2.5 lb/ft 5 G 0.85 4 ftarrow_forward
