Headed to Mars? Pack Some Aerogel—You Know, for Terraforming

It’s called a solid-state greenhouse effect—light penetrates the surface, passes through the translucent ice, and then hits darker regolith, which warms up. Could an insulating material create a solid-state greenhouse effect warm enough to make Mars habitable?

Should You Wear White or Black on Hot Days? Here's the Data

Perhaps the question should be: Does white reflect MORE thermal radiation than black clothing (I'm equating thermal radiation and infrared light—same thing). The T-shirts (both the black and the white) have an emissivity very close to 1—they don't really reflect much infrared radiation.

And, of course, they can complement that taste with the intoxicating experience of THC, like traditional chefs might pair foods with particular wines. Just like a tasting menu at a fine restaurant might come with wine pairings, heightening the experience both with additional flavors and drunkenness, so too might cannabis chefs use weed to augment a meal.

Simple Experiments Show How Motion Is Equivalent to Heat

Simple Experiments Show How Motion Is Equivalent to Heat

The change in thermal energy of an object depends on three things: the object's mass, the change in temperature, and the specific heat capacity (which depends on the material). In order to calculate the change in thermal energy, I need the specific heat capacity for the two materials (water and copper).

Oceans Are 'Spiking a Fever' With Record Heat Waves

The number of heat waves affecting the planet’s oceans has increased sharply, scientists have revealed, killing swathes of sea life like “wildfires that take out huge areas of forest.” The damage caused in these hotspots is also harmful for humanity, which relies on the oceans for oxygen, food, storm protection and the removal of climate-warming carbon dioxide the atmosphere, they say.

How Many Times Do You Have to Slap a Chicken to Cook It?

Since I know the heat capacity of water, I can use that decrease in temperature of the water to calculate the increase in thermal energy of the turkey. Conservation of Energy If I assume chicken is similar to turkey, I can calculate the change in thermal energy to cook it.

Why Electric Cars Struggle in the Cold—and How to Help Them

“You don’t have as much power when you want to discharge,” says Stefanopoulou, “The situation is even more limited when you want to charge.” Modern cars are designed to take that into account, with battery thermal management systems that warm or cool a battery.
