Answer: There are 0.373 kJ in 373 joules.
Explanation:
According to the standard conversion units 1 kJ is equal to 1000 J. This means that 1 J is equal to 0.001 kJ.
Hence, 373 joules is converted into kilojoules as follows.
Thus, we can conclude that there are 0.373 kJ in 373 joules.
Answer:
<em>56.4 m</em>
<em></em>
Explanation:
volume increases by factor of 6, i.e = 6
Initial temperature T1 at bottom of lake = 5.24°C = 278.24 K
Final temperature T2 at top of lake = 18.73°C = 291.73 K
NB to change temperature from °C to K we add 273
Final pressure P2 at the top of the lake = 0.973 atm
Initial pressure P1 at bottom of lake = ?
Using the equation of an ideal gas
=
P1 = =
P1 = 5.57 atm
5.57 atm = 5.57 x 101325 = 564380.25 Pa
Density Ρ of lake = 1.02 g/ = 1020 kg/
acceleration due to gravity g = 9.81
Pressure at lake bottom = pgd
where d is the depth of the lake
564380.25 = 1020 x 9.81 x d
d = = <em>56.4 m</em>
