Answer:
Standard boiling point
Explanation:
Note that there are 2 major units of pressure except Pa .
- bar
- atm
At 1 atm pressure the boiling temperature is called normal boiling point.
At 1 bar pressure the boiling temperature is called standard boiling point
Answer:
It's because of the presence of protons.
Explanation:
A nucleus of an atom has protons and neutrons. We know that a proton has a charge of
+
1
, while a neutron has no charge, or
0
. Therefore, the nucleus of an atom will always have a positive charge.
P1=1.0atm
P2=?
T1=20c=293k
T2=30c=303k
P1/T1=P2/T2
(P1/T1)T2
(1.00atm/293k)303k=1.03k
