Complete Question
Despite the destruction from Hurricane Katrina in Sept 2005,the lowest pressure for a hurricane in the Atlantic Ocean was measured several weeks after Katrina. Hurricane Wilma registered at atmospheric pressure of 88.2 kPa on Oct 19, 2005,about 2 kPa lower than Hurricane Katrinia. What was the difference between the two hurricanes in:
millimeters of Hg? ___ mm Hg
atmospheres? ___ atm
millibars? ___ mb
Answer:
The difference in pressure in mm of Hg is
The difference in pressure in atm is
The difference in pressure in millibar is
Explanation:
From the question we are told that
The pressure of Hurricane Wilma is
The difference is pressure is
Generally
The pressure difference in mm Hg is mathematically evaluated as
Substituting the value
The pressure difference in atm is
The pressure in millibars is

Answer:
16.1923 kj
Explanation:
Given data:
Mass of ice = 30.1 g
Initial temperature = -250 °C
Final temperature = 15.0 °C
Energy required = ?
Solution:
Specific heat capacity of ice is 2.03 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 = 15.0°C - (-250 °C)
ΔT = 265°C
Q = 30.1 g × 2.03 J/g.°C × 265°C
Q = 16192.3 J
J to kJ:
16192.3 J × 1 KJ /1000 j
16.1923 kj
