What is its final temperature if a glass jar of water initially at 28.9C but the water warmed by 1.7C each of 3 hours in the sun and lost 0.5C during each of the 4 hours it sat in shade?

T = 28.9°C + 1.7°C/hr × 3 hr - 0.5°C/hr × 4 hr
= 28.9°C + 5.1°C - 2 °C
= 32°C

A 1.50Kg iron horseshoe initially at 600 degrees C is dropped into a bucket containing 20.0Kg of water at 25.0 degrees C What is the final temperature?
You need the heat capacities for these substances in order to answer this question. If you have those, it's simple algebra.
If the temperature was -25c and rose 19c and then fell 8c?
If the temperature was -25°C and rose 19°C, it would reach a temperature of -6°C. If it then fell 8°C, the final temperature would be -14°C.
The pressure of 250 kPa acting on 15 cubic meters of a gas at a temperature of 100 K is increased to 500 kPa and the volume is increased to 30 cubic meters?
Use the ideal gas equation to solve this. PV= nRT. You will have to convert your pressure to atmosphere to use the constant R = 0.0821 L*ATM/mol*K. You know your initial pressure, volume, and temperature. Moles can be neglected (n) because they will stay the same. You also know your final pressure and final volume, so you can solve for final temperature.
Can you give some mathematical problems related to heat of fusion?
This is the formula for finding calories: calories= (Tf-Ti)mass Or, in words, you subtract the final temperature (the temperature of the fused waters) by its initial temperature (the hot/ cold water's original temperature). You then multiply this answer by the mass of the water before you mix them together. Your hot and cold water should both have the same mass, but not the same temperature.
What is the final temperature of a 48.26 g sample of aluminum at 100 degree Celsius dripped into 34.47 g of water at 25.0 degree Celsius?
42.3 C
If the water was initially at C what is its final temperature at a Kelvin scale of J?
The relation is:[K] = [oC] + 273,15
A 55 g aluminum block initially at 27.5 Celsius degrees absorbs 725J of heat what is the final temperature of the aluminuim?
9.14g
Suppose that 28 g of each of the following substances is initially at 27.0circ C What is the final temperature of each substance upon absorbing 2.45 kJ of heat?
We can answer this one of two ways. The first way we can do the experiment to a 'T' to find out the final temperature, or we can use the formula provided with our lab.
Calculate the final temperature when 50 ml of water at 80?
When allowed to stand for long enough, the final temperature will reach room temperature.

A hot metal bar is placed into cool water what statement is true?
The temperature of the metal bar decreases.The temperature of the cool water increases.The final temperature of the metal bar will be the same as the final temperature of the water.
Why do you use thermometer when you have fever?
We use the thermometer to measure the intensity of fever for final medical treatment recommendations. Normal human body temperature is 98.6 Fahrenheit. it must go up during fever. Different medicines recommended for different temperature intensity during fever.
When nitrogen stored at 6000 psi is released into the atmosphere what is it's temperature?
The final temperature will depend not only on the initial and final pressures, but also on the initial temperature and whether the expansion is adiabatic.
What is the final temperature when 0.032 kg of milk at 11 degrees Celsius is added to 0.16 kg of coffee at 91 degrees Celsius?
this is just a guess because both are mostly water, you would expect that the immediate final temperature would be 5/6 the way between 11 and 910C. So ~77.50C. Though because the mixing vessel is not warmed to this temp (heat capicity of calorimeter) along with the room temp playing a role, it will in practice be lower
How to calculate delta temperature?
To calculate the delta temperature, you will take the difference between the final and initial temperature.
