Why are styrofoam cups good for testing calorimetry of bombs?
Because syrofoam is a good insulator so it keeps most of the heat in the calorimeter. It also has a low specific heat
Chemistry calorimetry help?
Calorimetry measures the heat of chemical reactions and physical changes. The steps involved in solving calorimetry problems are as follows: The heat of the reaction is less than the amount of heat measured by the calometer. The heat gained by the calometer is the capacity of the calorimeter and temperature change of the sample undergoing the chemical and/or physical change. The combination of the two are calculated to heat reaction and given temperature change.
What is meant by calorimetry?
Measurement of the amount of heat evolved or absorbed in a chemical reaction, change of state, or formation of a solution
How do you find specific heat without the energy?
Use the equation: q=c*m*^TLet q be heat absorbed or released. c is the specific heat. m is the mass. Let ^T be change in heat.For example: Determine the specific heat of a material if a 12g sample absorbs 48J of heat as the temperature rises from 20`C to 40`C.48J=c*12g*(40`C-20`C)c= 0.20 J/g*`C
What is the unknown metal in the AP Chemistry Heat Effects and Calorimetry Lab?
that is supposed to be unknown until you figure it out.
What is the relationship between heat and calorimetry?
heat is a form of energy. where as "calorimetry" is the study of energy or study of heat. calorimetry not only deals with heat but also with other forms of energy.
What is the fomula to calorimetry?
The formula for calorimetry is Q = mcΔT, where Q is the heat energy transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature of the substance.
The words calorimeter calorimetry and calorie are all derived from the Latin word calor?
Yes, calor is the Latin word for heat.Calorimeter and calorimetry are connected with measuring heat, and a calorie is a unit of (heat) energy.
What is the specific heat of ceramic?
Using calorimetry in three separate trials, we found it to be 1063j/kgC. It is apparently more like 1090 and some error on our behalf is expected.
Why are styrofoam cups good for testing calorimetry of bombs?
Because syrofoam is a good insulator so it keeps most of the heat in the calorimeter. It also has a low specific heat
What is the specific heat of heat?
about 2300 (J/kg/°C) @ 23 °C

What is coppers specific heat?
The specific heat of copper is 0.093 cal/g(C°) or 390 J/kg(C°).
Write the expression and value for the specific heat of water?
The expression for specific heat is Q = mc(delta T) where Q is the heat added, c is the specific heat, m is the mass, and delta T is the change in temperature in degrees C. Specific heat is the amount of heat per unit of mass needed to raise the temperature by 1 degree C. The specific heat of water is 1 cal/gram degree C = 4.186 joule/gram degree C. Water has a higher specific heat than most common substances.
What are the principles of calorimetry?
Isothermal Principle: total heat elimination = heat loss by radiation + convection + conduction + evaporation
What method is used to measure the amount of heat given off by the body?
Direct calorimetry
What is meant by calorimetry?
Measurement of the amount of heat evolved or absorbed in a chemical reaction, change of state, or formation of a solution
