The dP/dt of the adiabatic expansion is -42/11 kPa/min
<h3>How to calculate dP/dt in an adiabatic expansion?</h3>
An adiabatic process is a process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression
Given b=1.5, P=7 kPa, V=110 cm³, and dV/dt=40 cm³/min
PVᵇ = C
Taking logs of both sides gives:
ln P + b ln V = ln C
Taking partial derivatives gives:
Substitutituting the values b, P, V and dV/dt into the derivative above:
1/7 x dP/dt + 1.5/110 x 40 = 0
1/7 x dP/dt + 6/11 = 0
1/7 x dP/dt = - 6/11
dP/dt = - 6/11 x 7
dP/dt = -42/11 kPa/min
Therefore, the value of dP/dt is -42/11 kPa/min

Answer:
30 short cakes
Step-by-step explanation:
25ml = 10ml + 10ml +5ml
each 10ml of milk can make us 12 short cakes
we can two 10ml of milk (20ml) which can make us 24 short cakes.
but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?
5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.
25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
