If 50 grams of a substance with a temp of 20 degree Celsius and specific heat of 2 is mixed with 200 grams of water with a temperature of 40 degree Celsius what will be the equilibrium temperature of?

Heat gained by one object has to equal the heat lost by the other object. The final temperature of the two objects will be the same.
Object 1:
mass1 = 50 g
initial T1 = 20 oC
Cg = 2 J/degree/gram
final T1 = Tf
Change in temperature = Tf - T1
Q = Cg x change in T x mass
= 2 x ( Tf - T1 ) x 50
Water:
Mass = 200 g
Cg = 4.18 J/ degree/ gram
Change in T = Tf - 40
Q = 4.18 x (Tf - 40) x 200
4.18 x (Tf - 40) x 200 = -(2 x ( Tf - 20 ) x 50)
Tf = 37.9 oC

What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
What is the temperature at which a substance may exist in all three phases?
The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.
What is specific temperature?
Specific temperature is an amount of heat per unit mass required to raise the temperature by one degree Celsius.
The measure of how hot or cold a substance is?
That would be its temperature expressed in degrees of Fahrenheit, Celsius or centigrade.
How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object. Historically the specific heat was related to SH of water . Water being 1 That now is seen as archaic. The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered. Every substance has to be measured separately .
Liquid changes into ice at what temperature?
Different depending on the specific substance, but water is 32 degrees Celsius.
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
What is the temperature at which a substance may exist in all three phases?
The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.
What is Celsius triple point?
The triple point of a substance is the temperature and pressure at which the three phases (gas,liquid, and solid) of that substance coexist in thermodynamic equilibrium. The triple point of water is 0.01 degrees Celsius and 0.00603659 atm. At that point, all of the substance can be changed into a liquid, solid, or gas by making small changes in temperature and pressure.https://en.wikipedia.org/wiki/Triple_point
What specific heat capacity?
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .however it obtained the unit of J/kg/kThe specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius._____________________Apex: The energy needed to change the temperature of a substance The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
What substance has a temperature of 273 kelvin's so what is its temperature in degrees Celsius?
If its temperature is 273K - it's Celsius equivalent is 0oC
What is specific heat capacity?
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
What is triple point of water?
The temperature at which all three phases of a substance can exist in equilibrium. This temperature occurs at only one pressure.
