At STP, carbon dioxide (CO2) usually behaves as a gas. When it is frozen, it behaves as a solid calleddry ice. If the temperature and pressure are both increased from STP above the critical point, CO2adopts properties that lie midway between a gas and a liquid. In this state, it beha...
Thinking critically, we can make a rational decision instead of an emotional one, we can find a solution that is more likely to work, and we are more likely to be able to tell if something is the right thing to do. All these are due to the fact that people involved in critical think...
for example. When a material becomes solid, it incorporates energy that constrains its lattice structure. At critical heat flux, as a certain amount of heat is pumped into the material, it reaches its melting point or gas transition temperature, and this bonding energy is released as latent ...

All these innovative tools can improve efficiency and accelerate cellular ultrastructure analysis. This understanding is critical for advancing knowledge in areas such as cell biology, neurobiology, disease mechanisms, and potential therapeutic interventions. ...
(where natural gas is treated with steam in the presence of a catalyst, such as nickel), produce greenhouse gases (called “gray hydrogen”) that will need to be captured or offset in the future. If the carbon produced in these processes is captured and stored, the resulting hydrogen is ...
It is hoped that COP28 will help keep alive the goal of limiting long-term global temperature rise to 1.5 degrees Celcius, as was agreed in the Paris Agreement.Achieving this goal depends largely on an effective transitioning from fossil fuels to clean energy sources.However, countries remain ...
A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
As a result of climate change, the Earth has experienced global warming, including the warmest decade on record between 2011–2020, according to the National Oceanic and Atmospheric Administration (NOAA). On the Earth’s surface, the average temperature is about 1.1°C (1.98°F) warmer today ...
Oil supply has also been affected byRussia’s invasion of Ukraine, sending gas prices in the U.S. skyrocketing in 2022.2 Examples of Supply Shocks The struggles of a single firm can cause a supply shock if the company is a large producer of high-demand products. This was the case when ...
