Answer:
3984.12 J joules of heat are required to heat 25.0 g of isopropyl alcohol to its boiling point.
Explanation:
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
We have 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:
3984.12 J joules of heat are required to heat 25.0 g of isopropyl alcohol to its boiling point.
Maglev trains were created to connect Shanghai Pudong International Airport to Central Pudong. Transrapid, another name for the Maglev train is said to be the fastest train. It can run up to 270/mph in just eight minutes.
Compared to other transportation systems, Transrapid is faster and more cost effective. It has less maintaining coverage and zero sounds compared to the ordinary ones.
This kind of train is one of the most effective means of transportation. It lessens traffic and pollution caused by car emission. It also saves more time for people who are always on the go.
Answer:
B) When the tilt of the Earth causes the sun’s energy/light to be spread out over a larger area, temperatures are ______warmer______ causing _____Summer_______ to occur.
There are no above options to choose from so I am giving an example of a X3Y2 formula which is Magnesium nitride, the formula is Mg3N2.
The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.
<h3>
What is volume?</h3>
Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.
Volume is measures in litres.
When water is added to dilute acid like HCl, they become more dilute.
When NaOH is added to HCl, a neutralization reaction occurs.
The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.
The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.
