A 48.26g sample of aluminum at 100.0C is dropped into 34.47g of water at 25.0C What is the final temperature?
To find the final temperature, you can use the principle of conservation of energy, Q lost = Q gained. The heat lost by the aluminum will be equal to the heat gained by the water. Use this formula: (mass of aluminum) x (specific heat capacity of aluminum) x (change in temperature) = (mass of water) x (specific heat capacity of water) x (change in temperature). You can then solve for the final temperature.
If water temp changes 15 degrees C how much heat was gained by the water?
To calculate the amount of heat gained by the water when the temperature changes by 15 degrees Celsius, you can use the formula: Q = mcΔT, where Q is the heat gained, m is the mass of water, c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the temperature change (15°C).
Show me a specific heat table?
Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius. A specific heat table provides values for specific heat capacities of various substances, typically in units of J/g°C. You can find specific heat tables in chemistry textbooks, reference books, or online resources.
What is the formula to find specific heat of water Q?
The formula to find the specific heat of water ( Q ) is: ( Q = mc\Delta T ), where (m) is the mass of the water, (c) is the specific heat capacity of water, and ( \Delta T ) is the change in temperature of the water.
How do you find the equilibrium temperature of a mixture?
To find the equilibrium temperature of a mixture, you can use the principle of conservation of energy, which states that the heat lost by the hotter substance must equal the heat gained by the cooler substance. Start by setting up the equation ( m_1c_1(T_f - T_1) = -m_2c_2(T_f - T_2) ), where ( m ) is mass, ( c ) is specific heat capacity, ( T_f ) is the final equilibrium temperature, and ( T_1 ) and ( T_2 ) are the initial temperatures of the two substances. Solve for ( T_f ) using the known values of mass, specific heat, and initial temperatures. Ensure that the units are consistent throughout the calculation.

Is heat energy gained by liquid equal to the heat energy lost by metal?
Not necessarily. The heat energy gained by the liquid and lost by the metal can be different because different materials have different specific heat capacities, meaning they require different amounts of energy to change temperature.
One hundred twenty grams of metal at 88 degree Celsius is poured into a 70 grams insulated cup contains 250 grams of water at 16 degree Celsius.The final temperature of the mixture is 17.5 degree celc?
To solve this problem, you can use the principle of conservation of energy: Heat gained by the metal = heat lost by the metal + heat gained by the water Plug in the given values and use the specific heat capacity of metal and water to calculate the initial temperature of the metal before mixing.
The amount of heat gained or lost by a substance is equal to the product of?

What is the specific heat problem and how does it impact the study of thermodynamics?
The specific heat problem refers to the challenge of accurately measuring and predicting the specific heat capacity of substances. This impacts the study of thermodynamics because specific heat capacity is a crucial parameter in understanding how substances store and release energy as heat. Inaccurate measurements can lead to errors in calculations and hinder the ability to predict and control thermal processes.
Why is the correct equation rearranged to solve for specific heat?
The equation for specific heat, Q = mcΔT, can be rearranged to solve for specific heat by isolating c, the specific heat, which gives c = Q / (mΔT). This rearrangement allows us to find the specific heat capacity of a substance based on the amount of heat energy transferred, the mass of the substance, and the temperature change it undergoes.
A metal object with mass of 19g is heated to 96 Celsius then transferred to calorimeter containing 75 grams of water at 18 Celsius It reaches a temperature of 22 Celsius What is the specific heat?
The specific heat capacity of the metal object can be calculated using the formula q = mcΔT, where q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. The heat gained by the metal is equal to the heat lost by the water in the calorimeter, so q_metal = -q_water. By setting up the equation and solving for c, you can find the specific heat capacity of the metal.
How can you find specific heat value at 600 C for a compound?
You have to know mass in grams, energy (q) gained or lost in Joules, and change in temperature,ΔT, in degrees C. ΔT = Final temp - initial temp. The specific heat = q/(m)(ΔT) = J/g•oC
What is a correct numerical set up for calculating the number of joules of heat gained by water?
To calculate the number of joules of heat gained by water, you can use the formula Q = m * c * ΔT, where Q is the heat gained, m is the mass of water in grams, c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the change in temperature in degrees Celsius. Plug in the values for m, c, and ΔT to calculate the heat gained in joules.
What is the dimensional formula of energy?
the formula to find specific heat is specific heat= calories/mass X change in temperature.
How can one determine the equilibrium temperature in a system?
To determine the equilibrium temperature in a system, you need to find the point where the rate of heat gained equals the rate of heat lost. This can be calculated using the specific heat capacities of the materials involved and the initial temperatures. The equilibrium temperature is the temperature at which the system reaches a stable state with no net heat transfer.
Q equals mass x specific heat x difference in temperature?
This formula relates heat (Q) with mass, specific heat, and temperature change. It is typically used to calculate the amount of heat energy gained or lost during a temperature change in a system. The formula shows that the heat exchanged is directly proportional to the mass of the substance, its specific heat capacity, and the temperature change.
