The Distant Past
An ionic compound must contain this kind of element
What is a metal?
According to the First Law of Thermodynamics, this cannot happen to energy
What is destruction?
Of the Joule, the small-c calorie (aka, "the chemistry calorie") and the capital-c Calorie (aka, "the food calorie"), the one that is the largest
What is the Calorie?
This is the reason that a calorimeter should have a very well insulated container
What is to avoid losing any heat during the experiment?
A recipe might ask you to boil in salt water for this reason that has nothing to do with flavor
What is to raise the boiling point so the food cooks at a slightly higher temperature?
Almost every atom wishes for this number of electrons in its outer shell (and some have it!!)
What is 8?
According to the First Law of Thermodynamics, this is the only thing that can happen to energy
What is changing forms?
The metric unit that you would use to describe "food calories"
What is a kilo-calorie?
This is the sign of q-object in the calorimetry equation
What is negative?
It's James Prescott's last name, now used as a unit of heat
What is a Joule?
Nitrogen protects us from these fatal rays that come from the sun
What are gamma rays?
Energy is released in this kind of chemical reaction
What is an exothermic reaction?
Of iron and water, the one with the lower specific heat
What is iron?
This constant is unique for each substance
What is specific heat?
The rightmost column of the periodic table contains these elements
What are the inert gases? Or what are the noble gases?
The freezing point of a solution will always have this relation to the freezing point of its solvent
What is a lower temperature?
The exhausted kindergarten teacher gazed with unfocused eyes at her very active students on the playground and lamented, "They have far too much of this kind of energy!"
What is kinetic energy?
This is how you calculate ∆T
What is final temperature minus initial temperature?
It's often not significant, so we can usually omit it in the calculation
What is the q-calorimeter?
The First Baron Kelvin discovered that there is a lower limit to temperature, which we call this
What is absolute zero, or minus 273.15°C?
You can tell you don't have complete combustion if you see this among the products
What is CO (carbon monoxide) or soot (just plain carbon)?
This is how much energy it would take to lift 102 paperclips from the floor to a height of 2 meters
What is 2 Joules?
If you have specific heat, change in temperature, and the amount of heat gained or lost, then you can calculate this
What is the mass of the object?
This is the specific heat of water in cal/g°C
This is the last naturally occurring element
What is uranium (#92)?
