A typical question...
Assuming no heat loss to the surroundings,
McDO = mcdo
Mass is proportional to volume. (Mass = density x volume)
=> MDO = mdo
=> 1 x (40 - O) = 2 x (O - 20)
=> 30 = 80
=> O = 26.7 oC (ANS)
Room temperature is the final temperature.
Assuming no heat is lost, the final three litre mix would be 33.33 degrees Celsius
1(T-20)= 2(40-T)
T-20=80-2T
3T=100
T=33.33
Because they are of equal volumes, the 20C and 40C will neutralize each other and reach an equilibrium of 30 C (assuming no other factors are present to affect the temperature)
30 degrees C
It will be 33.33... (repeating) deg C.

The temperature would be that of water's boilng point od 100 degrees
To calculate the temperature in degrees Fahrenheit from degrees Celsius, take the Celsius number multiplied by 9/5 (or 1.8) and add 32. To illustrate, if you wanted to find the equivalent of 0 degrees Celsius, you'd multiply 0 by 9/5, which would be 0, and add 32 for a final answer of 32 degrees Fahrenheit.
To convert temperatures in degrees Celsius to degrees Fahrenheit [°F] = [°C] × 9⁄5 + 32 To convert temperature in degrees Fahrenheit to degrees Celsius [°C] = ([°F] − 32) × 5⁄9
I believe it will be 145.52 degrees Celsius if I did my math correctly. You need to convert calories to joules. I believe one joule raises the temp of 1 gram water by 1 degree Celsius so 1200*4.184=5020.8 J /40grams=125.52 temp increase+20=145.52 degrees Celsius.
THE ANSWER IS 62.8 DEGREES.....

France uses the Celsius scale and the US uses the Fahrenheit scale. Tc = (5/9)*(Tf-32); Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. For example, suppose you have a Fahrenheit temperature of 98.6 degrees and you wanted to convert it into degrees on the Celsius scale. Using the above formula, you would first subtract 32 from the Fahrenheit temperature and get 66.6 as a result. Then you multiply 66.6 by five-ninths and get the converted value of 37 degrees Celsius. Below is the formula to convert a Celsius scale temperature into degrees on the Fahrenheit scale. Tf = (9/5)*Tc+32; Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. Assume that you have a Celsius scale temperature of 100 degrees and you wish to convert it into degrees on the Fahrenheit scale. Using the stated formula, you first multiply the Celsius scale temperature reading by nine-fifths and get a result of 180. Then add 32 to 180 and get the final converted result of 212 degrees on the Fahrenheit scale.

Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
If they're both the same substance, then the mixture will settle at 55° C. If they're different substances, then the final temp can be anything between 50° C and 60° C, depending on the substances.
I'll assume here that by "70 temperature" you mean "70 degrees Celsius". Basically, you have to calculate the average temperature of all of the water in the mixture, which will be the final temperature once it's well stirred. The 200 grams of water at 10 degrees represent 2/3 of the total amount of water (300 grams), so thus, multiply 10 by 2/3 to determine their contribution to the final temperature. You will get 20/3. The 100 grams of water at 70 degrees represent 1/3 of the total amount of water, so multiply 70 by 1/3 to determine their contribution to the final temperature. You will get 70/3. When you add together the two temperatures you get 90/3, which is equal to 30. Therefore, the final temperature is 30 degrees Celsius.
No, as both the temperatures are the same, you will get only 2 cups, each 50 degrees. You have to heat the cup to get 100 degree.
