What will be the temperature of water if 1 liter water of 30 degree Celsius mixes with 1 liter water of 50 degree Celsius?
The final temperature of the water after mixing will be the average of the initial temperatures, which is (30 + 50) / 2 = 40 degrees Celsius.
At 4 C the volume of 15 g of water was 15 cm3 At 20 C the volume of the same 15 g of water was 15.03 cm3 What effect did the increase in temperature have on the waters density?
The increase in temperature caused the density of the water to decrease. As the temperature rose from 4°C to 20°C, the volume of the water expanded slightly while the mass remained constant. This resulted in a lower density at the higher temperature.
Is water a solid at -40 degrees celsius?
Yes, water is a solid at -40 degrees Celsius. At this temperature, water freezes and turns into ice.
A gas occupies 4.5 liters of at stp what is its volume in liters at 40psi and 80 degrees C the volume remains constant A. 3.15 B. 1.25 C. 374.15 D. 31.5?
Volume of a gas at STP is 4.5 liters. To find volume at 40 psi and 80 degrees C, we use the ideal gas law: PV = nRT. At constant volume, we can ignore volume and rearrange to P1/T1 = P2/T2. Plugging in the values, we find the volume at 40 psi and 80 degrees C to be 1.25 liters. Hence, the right answer is B. 1.25.
What is -40 F is equal to c?
-40°F = -40°C
What volume of ice is created from 200cc of water?
The volume of ice created from 200cc of water is also 200cc. When water freezes, it expands slightly, but the volume change is minimal. Therefore, the volume of ice formed will be very close to the volume of water initially used.
What effects does negative 40 degrees Celsius on water?
At - 40 deg C, water is frozen.
How much water is 40 grams?
Since water has a density very close to 1 gram per cubic centimeter (it varies depending on temperature but never gets very far from 1 g/cc and is almost exactly 1 g/cc at 4 °C) 40 grams of water would also be 40 cubic centimeters of liquid water.

What is the volume of 5000kg of water?
The density of pure water at +4 degrees C, is 1 g/ml. The volume, then, of 5000 kg of water is 5000 liters.

A volume of water is heated from C to C what happens?
As the water is heated from 0°C to 4°C, it undergoes a phase change from a solid to a liquid, experiencing an increase in temperature while maintaining the same state (liquid water) until it reaches 4°C. At 4°C, water has its maximum density, after which further heating until 100°C will result in the water transitioning to a gas (steam) at its boiling point.
40 liters of gas were collected over water when the barometer read 622.0 mm Hg and temp was 20C what volume wuould dry gas occupy at standard conditions?
To find the volume of the dry gas at standard conditions (0°C and 1 atm), we need to correct for the water vapor using the vapor pressure of water at 20°C. The vapor pressure of water at 20°C is 17.5 mm Hg. Therefore, the pressure of the dry gas is 622.0 mm Hg (total pressure) - 17.5 mm Hg (water vapor pressure) = 604.5 mm Hg. Using the ideal gas law, we can calculate the volume of the dry gas at standard conditions.
What is a volume of 5.0 g pure water?
The answer depends on the temperature and pressure. At the pressure of 1 atmosphere, at 4 deg C the volume is at its minimum volume of 5.00014 millilitres. At 20 deg C it is 5.00898 ml At 100 deg C the volume increases to 5.21703 ml.
