In radioactivity and in collisions leading to nuclear breakup, the chemical identity of the nuclear target is altered whenever there is a change in the nuclear charge. In fission and fusion nuclear reactions in which unstable nuclei are, respectively, split into smaller nuclei or amalgamated into larger ones, the energy release far exceeds that of any chemical reaction.

We have completed Version of Minds On Physics the App. We also just released the Mac version of the app series. Users of smart phones, tablets, Chromebooks, and Apple computers will enjoy using this awesome program on their devices. It is a re-make of our popular Minds On Physics Internet Modules. on steroids. Learn about our exciting project and begin MOP-ping on your phone, tablet, Chromebook, and Mac. (Windows versions are under construction.) Students will appreciated the immediate feedback, the question-specific help, and the repeated opportunities to correct misconceptions. Teachers will appreciate the extensive progress reports provided by the App version of our Minds On Physics program.

Is heating zinc oxide a physical or chemical change?
Zinc oxide is a white powder. When heated strongly (above 855°C) it turns yellow but becomes white again when cold.
What happens is that the zinc oxide loses some of its oxygen when it is hot but this reaction is reversed on cooling. The hot zinc oxide absorbs some of the blue wavelengths of light making the reflected light look more yellow. The loss of oxygen makes it a reversible chemical chang e.
Note: For the Common Entrance exam you need to know about the colour change when zinc oxide is heated but not why it happens.
You will not be asked if it is a physical or chemical change.

The Teacher Toolkits provide teachers with packages of online resources (simulations, movies, animations, demonstration ideas, etc.) that are organized around a topic and a set of learning objectives. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.

The third law of thermodynamics states that the entropy at the absolute zero of temperature is zero, corresponding to the most ordered possible state.

Minds On Physics - Legacy Version is the browser-based, Shockwave-dependent version of Minds On Physics the App. Relying on the Shockwave plug-in and a collection of carefully crafted questions, the Legacy Version of MOPs seeks to improve students conceptions of physics. Formerly named the Minds On Physics Internet Modules, this Shockwave-delivered program combines interactive questioning modules with web-based instructional resources to engage students in an exercise in thinking, reflecting and learning. Students will enjoy using these for practice and teachers can use them as homework assignments.
