Temperature

The reflectivity of a surface is called its albedo. It is a measure of how much of the incoming radiation that hits a surface is reflected back without being absorbed. High-albedo surfaces reflect more light, while low-albedo surfaces absorb more light.

The boiloing point of toluene at atmospheric pressure of 760 mm (torr) is 110.5 deg C. Reducing the pressure lowers the boiling point. The boiling point of toluene at 600 mm (torr) is 104.0 deg C.

the more solvent you use the more of the poorly soluable compound (wich you are trying to crystallise) will be lost when you cool down your solvent.

because the soluability at the lower temperature is still not 0 g/l.

Chrome begins to discolor around 230 degrees Celsius, turning yellowish. As the temperature increases, the color may progress to blue, purple, and even brown.

At 20 degrees Celsius, copper is in its solid state. Copper has a melting point of 1,085 degrees Celsius, so at 20 degrees Celsius, it remains a solid metal.

Yes, a high temperature along with dry heaving can be a sign of illness or dehydration and should be evaluated by a medical professional. It could indicate a serious condition that requires treatment. Make sure to seek medical advice if you experience these symptoms.

The digital thermometer is more precise because it can measure temperature to one-tenth of a degree (20.7 degrees), while the bulb thermometer can only measure to whole degrees (21 degrees). The difference in precision is due to the digital thermometer's ability to provide more detailed readings.

Assuming temperature decreases at a standard lapse rate of about 6.5°C per kilometer, the temperature of the air at 500 meters would be approximately 23 degrees Celsius - (0.5 km * 6.5°C/km) = 20.25 degrees Celsius.

To convert Fahrenheit to Celsius, you can use the formula: Celsius = (Fahrenheit - 32) x 5/9.

In this case, for -346 degrees Fahrenheit, the conversion would be: Celsius = (-346 - 32) x 5/9 ≈ -209.4 degrees Celsius.

These two places have average temperatures that are sometimes slightly colder than the other. Sometimes New York is colder, and other times London. Although, yes, London is said to be colder than NY at times.

in general new york is colder than london. the average temp in london in jan is between 6 to 8 degrees and at night the average temp is 0 to 3 degrees however new york is much colder with average jan temps around 1 to 4 degrees and at night between -7 to -4 degrees however london can get pretty cold with temps not rising above 1 degrees with prolonged snow showers.

summer is a different story with temps in new york around 28 degrees and london around 23 degrees.

A temperature of 109 degrees Fahrenheit is a medical emergency and requires immediate medical attention as it can be life-threatening. It is not safe for an individual to go home with such a high fever.

The presence of water can lower the melting temperature of a rock by facilitating the transfer of heat and promoting the formation of liquid magma. Water can act as a flux, which helps to break chemical bonds in the rock and decrease its melting point. This process is commonly seen in the formation of magmas in subduction zones and other tectonically active regions.

Yes. Adding NaCl, sodium chloride, common table salt, lowers the freezing point of water by up to a few degrees. I was at a party where a couple of pounds of salt were added to an ice chest with a case of beer. The beer was room temperature, 70 degrees, and with only 10 pounds of ice, those beers were were at 32 degrees within 15 minutes. The temperature of the ice/water/salt solution was 26 degrees! I imagine it is the water that actually gets to 26 degrees after the salt melts it.

(-40) degrees Celsius = -40 degrees Fahrenheit and 233.15 kelvin.

5c is equal to 5 times c, which means 5 times any number represented by c.

A body temperature of 101.12 degrees Fahrenheit is considered elevated and may indicate a fever. It is recommended to monitor your temperature and seek medical advice if it persists or is accompanied by other symptoms.

This formula relates heat (Q) with mass, specific heat, and temperature change. It is typically used to calculate the amount of heat energy gained or lost during a temperature change in a system. The formula shows that the heat exchanged is directly proportional to the mass of the substance, its specific heat capacity, and the temperature change.

The thermosphere has high temperatures because it absorbs intense solar radiation due to its position in the atmosphere, causing the molecules to heat up. However, despite the high temperature, the thermosphere is not hot in the conventional sense as the density of the particles is very low, so a thermometer would not register the temperature as high as it feels.

The three main routes for taking a temperature are oral, rectal, and axillary (underarm). Oral measurements are taken in the mouth, rectal measurements are taken in the rectum, and axillary measurements are taken in the armpit. Each route can provide slightly different readings, so it's important to use the same method consistently for accurate comparisons.

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is about 95 degrees Fahrenheit.

Conversion from Fahrenheit to Celsius is done in three steps:

1. Subtract 32 from value in degrees Fahrenheit.

2. Multiply result of step 1 by 5.

3. Divide result of step 2 by 9.

Conversion formula: [°C] = ([°F] - 32) * 5 / 9 = (95 - 32) * 5 / 9 = 35 °C

In 28-degree water, you can survive for about 15-30 minutes before hypothermia sets in. However, your survival time can vary depending on factors like body size, body fat percentage, and clothing. It's crucial to get out of the water and warm up as quickly as possible.
