Answer:

The correct option is;

A warm front is approaching the city and temperatures will increase

Explanation:

A low pressure forms by the movement of air away from a particular spot such that the pressure reduces. The movement of air away from a spot occurs when there is a boundary of warm and cold air such that the air moves to maintain a uniform temperature.

Low pressure centers are associated with warm fronts, resulting in the fall of barometric pressure or observed low pressure and are characterized by a rise in temperature.

A 2.40 kg block of ice is heated with 5820 J of heat. The specific heat of water is 4.18 J•g^-1•C^-1. By how much will it’s temp
MrMuchimi

Answer: The temperature rise is 0.53^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed by ice = 5280 J

m = mass of ice = 2.40 kg = 2400 g   (1kg=1000g)

c = heat capacity of water = 4.18J/g^0C

Initial temperature  = T_i

Final temperature = T_f  

Change in temperature ,\Delta T=T_f-T_i=?

Putting in the values, we get:

5280J=2400g\times 4.18J/g^0C\times \Delta T

\Delta T=0.53^0C

Thus the temperature rise is 0.53^0C
