The time taken for the concentration of N2O to decrease to 32% of its initial concentration is calculated as follows
In(A1/A0)=-Kt
A1= final concentration = 32/100=0.32
A0= initial concentration =100/1000=1
K= constant= 0.76 per sec
time is therefore calculated as follows
In(0.32/1)= -0.76 t
-1.1394 =-0.76t divide both sid3es by -0.76
t is therefore= 1.5 s

Answer:
Melting
Explanation:
From solid to liquid, the change of state happening is the melting process. The kinetic energy of the particles that makes up the solid is increased and it allows the liquid to flow.
- A solid is a fixed mass with static molecules.
- When thermal energy is added, the kinetic energy increases.
- The kinetic energy of the particles increases and they vibrate about their fixed point in solids.
- This eventually breaks the structure and liquid which begins to flow forms.
This is a melting process.
Answer:
Due to electrostatic force
