The heat equation, as an introductory PDE.

In this video Paul Andersen describes the history of calorimetry and explains how it can be used to measure energy changes in a system. The specific heat of water is well established and so as a system releases or absorbs energy from a...

Today's episode dives into the HOW of enthalpy. How we calculate it, and how we determine it experimentally...even if our determinations here at Crash Course Chemistry are somewhat shoddy.

Mr. Andersen explains the difference between physical and chemical changes. A brief discussion of chemical reactions and equations is also included.

The heat equation, as an introductory PDE.

DIY SCI host Steve Spangler demonstrates that when a water bottle reaches the right temperature, you can watch it freeze right before your eyes!

When trying to determine or prove if a chemical reaction has occurred, there are 5 indicators that scientist look for! The 5 indicators are the formation of a precipitate, the formation of a gas, the formation of water, a color change or...

Mood rings are rings that have a stone or band that changes color in response to variations in temperature. They are also composed of liquid crystals, which undergo a change in color in response to changes in the temperature of the body...

In the application, for every change in temperature, all the observers get the notifications. In this video, we will see how billboard and simple display do not display the updated temperature if it is just a minor change.

The video is a lecture presentation about an experiment on the relationship between temperature and the rate of respiration in maggots. The speaker discusses the experimental setup, which includes placing maggots in a boiling tube with...

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different properties....

Describes what climate change really means and how it is affecting our temperatures

The video is a tutorial on how to investigate temperature changes in chemical reactions, specifically focusing on the concepts of exothermic and endothermic reactions. The video explains the definition of the two terms and provides...

A conversation with Steven Smith, Associate Director for International Space Station Science Directorate at NASA’s Ames Research Center in Silicon Valley.

The rebroadcast of a conversation with veteran astronaut Steven Smith, former Associate Director for International Space Station Science Directorate at NASA’s Ames Research Center in Silicon Valley.

The video is a lecture presentation about alcohols as fuels. The presenter explains how different alcohols react with oxygen in the air to produce carbon dioxide and water, and that these reactions are exothermic. The presenter then...

In this video lesson we will learn that we use the same rule for subtracting rational numbers as we did for subtracting integers. We will rewrite the subtraction problem to be an addition problem by adding the opposite value. Fondly...

This video is a lecture presentation on the thermal properties of water. The presenter discusses the specific heat capacity of water and how to calculate it using an equation. A student then demonstrates an experiment to determine the...

There are many built-in functions in Matlab to facilitate complex programming steps with few lines of code. Using built-in functions can save many hours of programming but also increases the amount that you must learn to master the...

Saturn's 2010 Great White Spot storm has set a new record for largest temperature change ever recorded for a storm on Saturn. By studying the monstrous disturbance using NASA's Cassini spacecraft, researchers spotted a massive belch...

Did you know that (at least) one mark in the HSC Chemistry exam comes from using the correct units? If you know your SI units well, then you’re guaranteed a free mark! If only the rest of the exam was that easy! This lesson will cover...

Learn the basics about Calorimeters and their uses.

Here, we perform a sample calculation for heat capacity in which we solve for a temperature (T) using q=smΔT.<br/>

In this video viewers will learn that heat of fusion is equal to the amount of heat that must be added or given off to melt or freeze one gram or kilogram of a substance and it’s expressed J/g or J/kg. Students will learn what units are...
