Calculate the final temperature when 50ml of water at 80 degree Celsius are added to 25 ml of water at 25 degree Celsius?
Okay, so we have some amount of water that is hot, and some amount of water that is cold. Mix em together and you will get something warm. At the end, both the hot water and cold water you started with will be the same temperature. If both will equal the same temperature at the end of the reaction, we can make them equal to each other and solve for "X".
s = specific heat (specific heat of water is 4.18 J/ degree Celsius x gram)
m = mass
(Tf - Ti) aka. "delta T" = change in temperature, Final - Initial.
However since one of them is losing heat and the other is gaining heat energy, the equation is:
qhot = - qcold
s1 x m1 x (Tf - Ti) = - s2 x m2 x (Tf - Ti)
(4.18 J / C x g) x (50.g) x (X - 60 C) = - (4.18 J / C x g) x (25g) x (X - 20 C)
DROP UNITS and solve for "X"
depending on whether you round or not, I'll put down exact numbers and round at end
209X - 12540 = - 104.5X + 2090
313.5X = 14630
X = 46.66666
In which case you can round it to 47 C.
So to sum it up, if you mix these two together, the final temperature will be 47 degrees Celsius.

What temperature does a phase change begin?
It will start to melt if the temperature rises above 0 degrees Celsius or 32 degrees FahrenheitOfficially, the melting temperature of ice is zero degrees Celsius (or 32F). The freezing temperature does vary dependent on the electrolytes added to the water solution. For example, ocean water (salt water), freezes at ~-18 degrees Celsius (or 0F). Various solutions at different concentration of solute offer various degrees of melting/freezing. At 0 degrees Celsius.
If a bucket with 55 liters of hot water at 45 celsius is added to 45kg of water at 1 c what is the final temp of the water?
To find the final temperature of the water, we can use the principle of conservation of energy, which states that the total energy of the system remains constant. By using the formula: (mass1 * specific heat1 * change in temperature1) = (mass2 * specific heat2 * change in temperature2), we can calculate the final temperature to be approximately 13.3 degrees Celsius.
What is required to change the state of water?
To change the state of water from solid (ice) to liquid (water), heat must be added to increase the temperature above 0 degrees Celsius. To change water from liquid to gas (water vapor), heat must be added to increase the temperature above 100 degrees Celsius.
If a solid piece of naphthalene is heated and remains at 80 degrees Celsius until it is completely melted you know that 80 degrees Celsius is?
80 degrees Celsius is the melting point of naphthalene. At this temperature, the solid naphthalene transitions to a liquid state, and the temperature remains constant during the phase change until all of the solid has melted. This characteristic indicates that the energy being added to the system is used for breaking intermolecular forces rather than increasing temperature.
Do you add a degree when taking temperature from the ear?
No, a degree is not typically added when taking a temperature from the ear. The temperature reading from an ear thermometer is already in degrees Celsius or Fahrenheit, so there is no need to add a degree to the result.
Do you add a degree with digital thermometer?
No, digital thermometers display temperature readings in degrees Celsius or Fahrenheit without requiring an additional degree to be added. Just read the displayed temperature directly from the device.
Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?
pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.

If 1200 calories of heat is added to 40 grams of water at 20 degree what will be the final temperature?
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.
How do you calculate the average temperature?
To calculate the average temperature, you add up all the temperatures and then divide by the number of temperatures you added together. This gives you the average temperature.
How many grams of NaNo3 would have to be added to a 100 gram of water at 45 degree Celsius?
To calculate the amount of NaNO3 needed to form a saturated solution at 45°C, the solubility of NaNO3 at this temperature must be known. Once this value is determined, the grams of NaNO3 required can be calculated using the solubility value and the saturation point equation.
What happens if energy is added to a liquid at 20 Celsius?
If energy is added to a liquid at 20 Celsius, the temperature of the liquid will increase. This can lead to a phase change if the added energy is sufficient to raise the liquid's temperature above its boiling point, causing it to vaporize. If the added energy is not enough for a phase change, the increased temperature can affect the liquid's properties such as viscosity.
What degree celsius does water change from liquid to gas?
I'm pretty sure that it is a 100 degree Celsius because when water is boiling it becomes a gas so I think I'm right Added: But it is dependant of pressure. When you are high in the mountains water is boiling easier and at lower temperature because of the lower pressure (Henry's Law, I believe). Boiling eggs in boiling water at 95 oC will take significantly longer!
Why is it easy to cool lime juice with ice cubes than adding water at 0 degree C?
Ice cubes at a lower temperature (below 0 degrees Celsius) have more capacity to absorb heat compared to water at 0 degrees Celsius. When added to lime juice, the ice cubes can cool the juice more effectively due to their lower temperature and phase change from solid to liquid. This causes a larger drop in temperature of the lime juice compared to adding water at 0 degrees Celsius.
