How much energy is required to change 110 grams of steam at 181 C to 40 C

Q = -64893.84 J

Explanation:

Given data:

Mass of steam = 110 g

Initial temperature = 181 °C

Final temperature = 40°C

Energy released = ?

Solution:

Energy will released in this process because temperature is going to be decreased.

Specific heat capacity of water is 4.184 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 40°C - 181 °C

ΔT = -141°C

Q =  110 g × 4.184 J/g.°C × -141°C

Q = -64893.84 J

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
