Thermodynamics is the foundational branch of physical science concerned with the macroscopic relationships between heat, work, temperature, and energy. Its primary goal is to establish the fundamental laws that govern the transfer of energy from one place to another and from one form to another, as well as to determine the spontaneity and direction of physical and chemical processes.

Thermodynamics: In-Depth Description

To study the vast array of energy exchanges in nature, thermodynamics is divided into several specialized sub-disciplines

#Introduction I am Gregor Kos, a Senior Lecturer at #Concordia University in #Montreal, #Canada.

I teach #Thermodynamics, #AnalyticalChemistry, Introductory Research Methods and #MachineLearning for Chemists and Biochemists. I am working on hyper-local urban air quality using low-cost sensors.

#Présentation Gregor Kos, maître de conférences à l'Université Concordia de Montréal, au Canada.

J'enseigne la #thermodynamique, #chimieAnalytique, les méthodes de recherche et l'apprentissage automatique (machine learning) aux chimistes et aux biochimistes. Je mène des travaux de #recherche sur la #qualité de l'air en environnement urbain à l'échelle hyper-locale à l'aide de capteurs à faible coût.

How Clean Air Warms the Earth

Today, we’re exploring a microscopic landscape completely invisible to the naked eye—a world of 'ghost' particles that control both our climate and our own biology.

Cooling is rarely steady. Experiments show how heat transfer changes dynamically during rapid temperature drops.

These transient effects matter for boiling regimes and could help refine models of vapor layer formation.

Oh, look! Another #academic trying to make #thermodynamics sound interesting by slapping on fancy words and #outdated #references. 📚👉👴 For those who enjoy #reading #verbose #papers about imaginary demons in their spare time, this one’s for you. Otherwise, it’s just 650 words you’ll never get back. 🤦‍♂️

The #ecological hybrid dryer is an advanced #agricultural dehumidification device designed specifically for high-latitude regions with cold but highly illuminated "northern" summers. It utilizes solar energy combined with a thermal-storage core to provide continuous, 24-hour food dehydration without relying on conventional electrical grids.

International Team of Scientists Developed an Ecological Dryer for "Northern" Summer

Such an air dryer can be used not only for drying vegetables or fruits, but also mushrooms, berries, herbs, and grains.

Which is more energy efficient: heating a given volume of water all at once, or in two batches?

I have an electric kettle, and a large urn of room temperature filtered water, which I use for tea. If I'm making tea for two people who aren't going to be drinking it at the same time, is it more energy efficient to boil the water separately, all at once, or no difference?

Does #ElonMusk know this?

In this deep, #physics-inspired exploration, we break down the harsh scientific realities behind #Mars colonization: from irreversible arrow of time 2 #radiation damage, low-gravity #biology, & the hidden engineering challenges most people ignore. While #space agencies & tech visionaries dream of cities on Mars, the laws of #thermodynamics, biology, & cosmic physics tell a far more complicated story
