To calculate the final temperature when two substances at different temperatures are mixed, use the principle of conservation of energy, which states that the heat lost by the hotter substance equals the heat gained by the cooler substance. The formula is: ( m_1 c_1 (T_f - T_1) + m_2 c_2 (T_f - T_2) = 0 ), where ( m ) is mass, ( c ) is specific heat capacity, ( T_f ) is final temperature, and ( T_1 ) and ( T_2 ) are the initial temperatures of the two substances. Rearrange the equation to solve for ( T_f ). Ensure that all units are consistent for accurate results.

What is flormula for final temperature?
The formula for calculating the final temperature in a thermal equilibrium scenario is derived from the principle of conservation of energy. When two substances at different temperatures come into contact, the final temperature (Tf) can be calculated using the equation: ( m_1c_1(T_f - T_1) + m_2c_2(T_f - T_2) = 0 ) where ( m ) is the mass, ( c ) is the specific heat capacity, and ( T ) is the initial temperature of each substance. Rearranging this equation allows for the determination of the final temperature based on the initial conditions and properties of the substances involved.
How do you calculate the mercury rise in a thermometer?
To calculate the mercury rise in a thermometer, you need to subtract the initial temperature reading from the final temperature reading. The difference between these two readings represents the mercury rise in the thermometer. Make sure to use the units of measurement (usually degrees Celsius or Fahrenheit) in your calculation.
If 2.5kg of hot water at 100c is added to 10kg of cold water at 28c and stirred well what is the final temperature of mixture?
if 2.5kg of hot water at 100c is added to 10kg of cold water at 28c and stirred well. what is the final temperature of mixture? (neglect the heat absorbed by container and the heat lost by the surroundings.)
Can two substances have the same specific heat?
Yes, it is possible for two substances to have the same specific heat if they have similar atomic or molecular structures. However, it is more common for substances to have different specific heat values based on their composition and the way their atoms or molecules interact with heat energy.
Does the final temperature from the experiment equal to the final temperature from the calculation?
The final temperature from the experiment may not always equal the final temperature from the calculation. Experimental conditions, equipment limitations, and human error can all contribute to discrepancies between the two values. It is important to consider sources of error and variation when comparing experimental and calculated results.
How to find the final temperature when two substances are mixed together?
To find the final temperature when two substances are mixed together, you can use the formula: (Tf frac(m1 times C1 times T1) (m2 times C2 times T2)(m1 times C1) (m2 times C2)) Where: (Tf) is the final temperature (m1) and (m2) are the masses of the substances (C1) and (C2) are the specific heat capacities of the substances (T1) and (T2) are the initial temperatures of the substances Simply plug in the values for the masses, specific heat capacities, and initial temperatures of the substances to calculate the final temperature.
If a cold piece of metal is placed in an equal mass of warm water will the final temperature be closer to the original temperature of the metal or the water?
The final temperature will be closer to the original temperature of the water. Heat will flow from the water to the metal until they reach thermal equilibrium, resulting in a final temperature between the original temperatures of the two substances.
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?
To find the final temperature of each substance, you need to calculate the specific heat capacity of each substance. Once you have the specific heat capacity, you can use the formula Q = mcΔT to find the final temperature. Substituting the given values into the formula will give you the final temperature of each substance.

How can one determine the temperature change in a given system?
To determine the temperature change in a system, one can measure the initial and final temperatures using a thermometer and then calculate the difference between the two readings. This difference indicates the temperature change in the system.
Can heat transfer occur when two substances are the same temperature?
No, heat transfer occurs due to a temperature difference between two substances. If both substances are at the same temperature, there is no temperature gradient to drive heat transfer, so no heat transfer will occur.
When kg of water at degrees is added to kg of water at degrees what is the final temperature?
To find the final temperature after mixing the two amounts of water, you can use the principle of conservation of energy. The specific heat capacity of water is 4.18 J/g°C. Calculate the total energy gained or lost by each portion of water and set them equal to each other to solve for the final temperature.
What is the final temperature of a 3.0kg bar of gold at 99 degrees Celsius dropped into 0.22kg of water at 25 degrees celsius?
To find the final temperature, we can use the principle of conservation of energy: heat lost by gold = heat gained by water. We can use the formula m * c * ∆T to calculate the heat exchanged. By setting the two heat exchanges equal to each other and solving for the final temperature, we can find that the final temperature is 25.9 degrees Celsius.
When two substances come into contact with each other the substance will transfer heat to the substance?
When two substances come into contact, heat will flow from the substance with higher temperature to the substance with lower temperature. This transfer of heat will continue until thermal equilibrium is reached, where both substances have the same temperature.

Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
Yes, the greater the difference in temperature between two substances, the faster heat transfer will occur between them. This is because heat naturally flows from areas of high temperature to areas of low temperature in an attempt to reach equilibrium.
