Answer:
The final temperature of water is <u>20.5061 °C.</u>
Explanation:
Let the final temperature of water be 'x'.
Given:
Heat added to water is, 
Initial temperature of water is, 
Mass of water is, 
Now, heat is added to water and its temperature is increased. The temperature is increased because water absorbs all the heat.
Heat absorbed by water is given as:
where 'c' is specific heat capacity of water and its value is equal to 4.186 J/g °C.
Now, plug in the given values and simplify.
Now, from law of conservation of energy, we know that:
Heat absorbed by water = Heat added to water
So, the final temperature of water is 20.5061 °C.
The answer should be 2.4 meters.
O
the amount of heat required to increase the temperature of 1 gram by 1°C
Explanation:
The specific heat of a substance is the amount of heat required to increase the temperature of 1 gram of a substance by 1°C. It is an intensive property that is specific to every substance.
The unit is given as J/g⁻¹°C⁻¹ or J/g⁻¹K⁻¹
This related to the quantity of heat using the expression below:
Q = mC∅
Q is the quantity of heat added
m is the mass
C is the specific heat
∅ is the temperature change.

Answer:
The answer to your question is V2 = 825.5 ml
Explanation:
Data
Volume 1 = 750 ml
Temperature 1 = 25°C
Volume 2= ?
Temperature 2 = 55°C
Process
Use the Charles' law to solve this problem
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Convert temperature to °K
T1 = 25 + 273 = 298°K
T2 = 55 + 273 = 328°K
-Substitution
V2 = (750 x 328) / 298
-Simplification
V2 = 246000 / 298
-Result
V2 = 825.5 ml
Answer:
Most organic compounds contain carbon and <u>hydrogen</u>.
Explanation:
Organic compounds are class of compounds which mainly constitute carbon and other elements like hydrogen, oxygen, nitrogen and sulfur etc.
In these compounds hydrogen is essentially present along with carbon as both make the basic organic class of compounds namely, Alkanes (saturated hydrocarbons), Alkenes and Alkynes (unsaturated hydrocarbons).
While remaining classes of organic compounds are derived from these three classes of hydrocarbons. Therefore, we can conclude that organic compounds are basically made up of carbon and hydrogen.
