How many joules of heat are required to heat 25.0 g of isopropyl alcohol from the prevailing room temperature, 21.2 oC, to its boiling point, 82.4 oC? The specific heat of isopropyl alcohol is 2.604 J/g °C.

The heat required to heat 25.0 g of isopropyl alcohol to its boiling point is 3984.12 Joules.

Explanation:

Mass of isopropyl alcohol = m = 25.0 g

Specific heat of isopropyl alcohol  = c = 2.604 J/g°C

Initial temperature of the isopropyl alcohol =

Final temperature of the isopropyl alcohol =

Heat absorbed by the isopropyl alcohol to boil: Q

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance  

ΔT = change in temperature of the substance

= Initial temperature of the substance

= Final temperature of the substance

On substituting the values  :

The heat required to heat 25.0 g of isopropyl alcohol to its boiling point is 3984.12 Joules.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

oh it is true if thats what you are asking
