How much heat is absorbed by water when 250g of iron is heated from 27 degrees Celsius to 300 degrees Celsius?
q = (250 g)(0.46 J/gC)(300 C - 27 C) = 3.1 X 104 Joules -------------------------
What is the final volume of a balloon that was initially 500.0 mL at 25 degrees Celsius and was then heated to 50 degrees Celsius?
Change Celsius to Kelvin by adding 273.15. 25 C = 298.15 K 50 C = 323.15 K An equality. 500.0 ml/298.15 K = X ml/323.15 K 298.15X = 161575 X = 541.925 milliliters -------------------------------you do significant figures
Why is a fermenter heated at 120 degrees?
A fermenter is heated to 120 degrees Fahrenheit (approximately 49 degrees Celsius) to create an optimal environment for microbial activity, particularly for certain yeast and bacteria involved in fermentation processes. This temperature helps to accelerate metabolic rates, enhancing the production of desired fermentation products, such as alcohol or organic acids. Additionally, heating can help inhibit the growth of undesirable microorganisms, ensuring a more controlled and efficient fermentation process.
What to wear in 90 degrees?
Shorts and a tank top. You don't want to get over heated.
How many BTU to reach 900 deg C?
To determine the amount of BTU (British Thermal Units) required to reach a temperature of 900 degrees Celsius, you need to know the mass of the substance being heated and its specific heat capacity. The formula to calculate the BTUs required is: BTU = mass (lbs) × specific heat (BTU/lb°F) × temperature change (°F). Since 900 degrees Celsius is equivalent to 1652 degrees Fahrenheit, the energy required will vary based on the material you are heating. For an accurate calculation, specific details about the material's mass and specific heat capacity are needed.
Which substance changes state when heated from 10 degrees Celsius to 80 degrees Celsius?
Water changes state from a liquid to a gas when heated from 10 degrees Celsius to 80 degrees Celsius.
In which degree Celsius water heated?
100 degrees celsius
What state of matter is ethanol at 100 degrees celsius?
Ethanol is a liquid at 100 degrees Celsius. It boils at 78.4 degrees Celsius, so at 100 degrees Celsius it would be in a gaseous state if it were heated beyond its boiling point.
What happens to copper oxide when its heated?
if it is heated above 1200 degrees celsius than it melts
What is the unusual behavior of water as it is heated from 0degrees Celsius to 15 degrees Celsius?
1,000 m
Can chloroform be heated to ninety degrees celsius in an open container?
Yes, chloroform can be heated to 90 degrees Celsius in an open container as long as proper caution is taken due to its flammability and toxicity. It is important to handle chloroform carefully and in a well-ventilated area to avoid any risks.
How many kilocalories were absorbed by the water iif you have 175g of water and it was heated from 15 degrees celsius to 88 degrees Celsius?
12.775 kcal
What does water do as it is heated?
it will boil once it reaches 100 degrees Celsius
Is heated copper oxide a solid liquid or gas?
Copper(I) oxide has a melting point of 1201 degrees Celsius, and a boiling point of 2000 degrees Celsius. Copper(II) oxide has a melting point of 1235 degrees Celsius, and a boiling point of 2000 degrees Celsius.
What happens to chromium when heated at 20 degrees Celsius?
Nothing, a passivation occur.
What is the mercury's motion particles as it's heated from 45 degrees Celsius to 365 degrees Celsius?
As mercury is heated from 45 degrees Celsius to 365 degrees Celsius, its particles will gain energy and move faster. This increased thermal energy causes the particles to vibrate more quickly and spread out, leading to an expansion in volume. At the higher temperature, the motion of mercury particles will be more rapid and chaotic compared to when it was at 45 degrees Celsius.
How cold is 60 degrees Celsius?
60 degrees Celsius is very hot, equivalent to 140 degrees Fahrenheit. At this temperature, it would be dangerous to touch anything that has been heated to 60 degrees Celsius without proper protection.
