18) The amount of radiation that an individual absorbs depends on?

On the amount of radiation emitted; on how close the individual is to the source of the radiation; on any objects in between which might absorb part of the radiation.


Convert -259 degrees Celsius temperature to kelvin?

When converting from Celsius to Kelvin you always add 273.15 and subtract the same amount when converting from Kelvin to Celsius thus: -259+273.15=14.15 The answer is 14.15 Kelvin


What will the temperature be if you mix 100 Celsius water and 7 degrees water?

The final temperature will be a value between 7 and 100 degrees Celsius, depending on the amounts of each water and their specific heats. This can be calculated using the principle of energy conservation in a calorimetry equation.


Which has more heat one liter of liquid at 80 degrees Celsius or a ten liter container at 80 degrees Celsius?

The ten liter container at 80 degrees Celsius would have more heat because it has a higher thermal capacity due to its larger volume. Heat is directly proportional to the amount of substance present, so a larger container will contain more heat energy.


What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?

The amount of heat energy required to change the temperature of a substance is given by the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Given that Q = 2646 J, ΔT = 15 °C, and for water c = 4.18 J/g°C, we can calculate the mass of water as follows: 2646 J = m * 4.18 J/g°C * 15 °C. Solving for m, we find that the mass of water required is approximately 40 g.

What does degrees Celsius measure?

Degrees Celsius measures temperature. It is a unit of measurement commonly used to quantify the amount of heat in a system.


How do you turn degrees kelvin into degrees Celsius?

To convert kelvin to Celsius, subtract 273.15 from kelvin. So if you are at 273.15 kelvin, you are at zero degrees Celsius. The above is almost true. 0 degrees Kelvin is equivalent to (minus) - 273.15 degrees Celsius. So you would need to add that amount to reveal the temperature in degrees Celsius.


Is 2 degrees Celsius colder than 6?

Yes, 2 degrees Celsius is colder than 6 degrees Celsius. The numerical value of the temperature indicates the amount of heat energy present, so a lower number represents a lower temperature. In this case, 2 degrees Celsius is 4 degrees lower than 6 degrees Celsius.


You have 100 liters of H2O at 25 degrees Celsius and you add 50 liters of H2O to it. What temp. does the 50 liters of H2O need to be for the total amount of H2O to equal 35 degrees Celsius?

100 degrees Celsius


Does the color of cloths you're wearing affect the amount of heat you absorb?

Yes, dark clothing absorbs the most.


Is 25 degree Celsius considered cool?

25 degrees Celsius is typically considered comfortable or mild, but not cool. Cool temperatures are usually considered to be around 15-20 degrees Celsius.


What would be the amount in Fahrenheit if the temperature changed 6 degrees Celsius?

Fahrenheit would change 10.8 degrees.


Does pair of eyeglasses absorbs light?

The lenses absorb a very small amount of light, transmitting most of it. If the frame of the glasses is made of a dark material, it will absorb most light.


How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?

To find the amount of KCl that remains in solution at 20 degrees Celsius, you can use the principle of solubility. Calculate the maximum amount of KCl that can dissolve in 200g of water at 20 degrees Celsius using a solubility chart. Once you have this value, compare it to the initial 80g of KCl to determine how much remains in solution after cooling.


What common substance requires the most energy to heat up a unit mass by 10 degrees Celsius?

Water requires the most energy to heat up compared to other common substances. This is because water has a high specific heat capacity, meaning it can absorb and retain a significant amount of energy before its temperature increases by 10 degrees Celsius.


How much does water does sparkle absorb?

From my experience, there wouldn't be an actual fixed amount, simply because the amount of water absorb is never truly constant. Also, each towel absorbs a slightly different amount of water. This makes it almost impossible to get a constant, fixed amount. I hope I was helpful.


What is the henrys law constant at 60 degrees Celsius and -10 degrees Celsius?

The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas.
