To find the change in temperature of the water, you can use the principle of conservation of energy, specifically the equation (m_1c_1(T_1 - T_f) = m_2c_2(T_f - T_2)). Given that the iron bar and water reach thermal equilibrium, you can solve for the final temperature (Tf) of the system. Once you calculate Tf, you can find the change in temperature of the water by subtracting the initial temperature of the water from Tf.

How many moles of N2 are there at a temperature of 20 degrees Celsius 1 ATM pressure if the gas occupies 44 Liters?
The answer is 1,83 moles.
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 303K and volume at 25L?
303K refers to a temperature of 303 Kelvin, which is equivalent to approximately 30 degrees Celsius. "Volume at 25L" typically means the volume of a substance is 25 liters, indicating the amount of space that substance occupies.
In order to get 10 percent HCl how much liters of water is needed when combined with 0 Celsius degrees 0.7 atmosphere pressure and 160 liters of HCl and The answer is 1.64l so how do u solve it?

What will be the volume of 1g of helium at ntp in liters?
At NTP (standard temperature and pressure), which is 0 degrees Celsius and 1 atm pressure, the volume occupied by 1 gram of helium would be approximately 22.4 liters. This value is based on the ideal gas law and the molar mass of helium.
You have 100 liters of H2O at 25 degrees Celsius and you add 50 liters of H2O to it. What temp. does the 50 liters of H2O need to be for the total amount of H2O to equal 35 degrees Celsius?
100 degrees Celsius
How many liters of cold water from the fridge at 4 degrees Celsius would you have to drink to burn 330 kilocalories to heat it up to body temperature at 37 degrees Celsius?
To raise the temperature of 1 liter of water by 1 degree Celsius, it requires 1 kilocalorie. Therefore, to burn 330 kilocalories and heat cold water from 4 degrees Celsius to 37 degrees Celsius, you would need to drink 33 liters of cold water.
Is 50 grams 96 degrees Celsius 148 meters or 259 liters a measurement of volume?
50 grams and 96 degrees Celsius are not measurements of volume. The options provided are not related to volume either; 148 meters is a measurement of length and 259 liters is a measurement of volume.
How many moles of N2 are there at a temperature of 20 degrees Celsius 1 ATM pressure if the gas occupies 44 Liters?
The answer is 1,83 moles.

How big is a gram of oxygen?
A gram of oxygen is equivalent to approximately 0.56 liters at standard temperature and pressure (STP), which is 0 degrees Celsius and 1 atmosphere of pressure.
A 2 liters tank contains air at 1atm and 20 degrees celsius.the tank is sealed and heated until the pressure is 3 atm.what is the temperature in degrees celsius?
Using the ideal gas law, (PV = nRT), we can solve for the final temperature using the initial conditions and new pressure. Rearranging the equation to solve for T, we get (T = (P2/P1) * T1), where T1 is the initial temperature. Substituting the values, we find the final temperature to be 80 degrees Celsius.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
To raise the temperature of 1000 liters of water by 10 degrees Celsius, you would require approximately 239 kilowatt-hours of energy. This can be calculated using the specific heat capacity of water and the formula for calculating energy required for temperature change.
