TOOL BOX q=mc∆T Water sp. Heat

Calorimetry : the measurement of energy (calorie)

Calorimeter : tool used to measure energy by Measuring the change in temperature

Equation : q=mc∆T What is the difference between Calorimetry and Calorimeter?

Quantity of
Energy (Cal.)

Mass
(g)

Specific heat (given) (Cal/g)

Change in temperature (℃ )
(End-short)

What is the dance that we learned in class today about our new equation?

Name all the Specific heat type and what they vary? ( if that makes sense)

Specific heat • Unique to every substance • Amount of energy required to increase 1g of substance by 1℃

High specific heat • Needs large amount of energy to change temp ex. Water
Low specific heat • Changes temp. easily ex.metal

Summary:

In today's class we talked a about the equation(s) of calorimetry. Calorimetry is the measurement of energy , and Calorimeter Is a tool used to measure energy by measuring the change in temperature. We also learn about the Specific heat, high specific heat, and low specific heat. But the main thing is that the new equation we learn today is

q=mc∆T

Calorie : Unit of energy Metry : Measurement Calorimetry : • Measurement of energy Energy : The ability to do work
Types of Energy : Kinetic & Potential

Movement

Stored

Heat

Chemical

Energy Laws : Laws of thermodynamics 1st Law : Energy cannot be created or destroyed, only transferred, or transformed 2ed Law : When energy is transformed or transferred, it becomes less useful ( "Lost" as heat )

Energy : energy flows like water • From high to low
