How valid is the assumption that the initial temperature of the steam is 100 degrees celsius?
The assumption that the initial temperature of steam is 100 degrees Celsius is generally valid when referring to saturated steam at atmospheric pressure. However, it's important to consider that the temperature of steam can vary depending on the pressure or if it is superheated. Additional information or measurements may be needed to confirm the exact initial temperature of the steam in a specific scenario.

Explain why increasing temperature from 3 degrees Celsius to 6 degrees Celsius does not double temperature?
Doubling temperature means increasing it by a factor of 2. In this case, going from 3 to 6 degrees Celsius represents an increase of 3 degrees, not a doubling of the initial temperature. To double the initial temperature of 3 degrees Celsius, it would need to increase to 6 degrees x 2 = 12 degrees Celsius, not just 6 degrees.
A 2 liters tank contains air at 1atm and 20 degrees celsius.the tank is sealed and heated until the pressure is 3 atm.what is the temperature in degrees celsius?
Using the ideal gas law, (PV = nRT), we can solve for the final temperature using the initial conditions and new pressure. Rearranging the equation to solve for T, we get (T = (P2/P1) * T1), where T1 is the initial temperature. Substituting the values, we find the final temperature to be 80 degrees Celsius.
If the temperature is curently 45 degrees and drops to -4 degrees in 7 hours which number shows the change in temperature?
The change in temperature is 49 degrees, calculated by subtracting the final temperature (-4 degrees) from the initial temperature (45 degrees).
How fast does temperature increase when ice is taken from a freezer and placed in a room temperature of 24 degrees Celsius?
The rate at which the temperature of ice increases when taken out of a freezer and placed in a room at 24 degrees Celsius depends on factors like the initial temperature of the ice and the specific heat capacity of ice. Typically, ice will start melting immediately upon exposure to a temperature higher than its melting point of 0 degrees Celsius. The rate of temperature increase will be faster in the beginning and may slow down as the ice starts melting and absorbing more heat.
500cm3 of ideal gas at 40 degrees Celsius and 200kpa absolute is compressed to 250cm3 and cooled to 20 degrees Celsius.What is the final absolute pressure?
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
If i have the initial and after temperature how would i be able to find the change in temperature?
You can find the change in temperature by subtracting the initial temperature from the final temperature. For example, if the initial temperature is 20 degrees Celsius and the final temperature is 30 degrees Celsius, the change in temperature would be 10 degrees Celsius (30 - 20 = 10).
Explain why increasing temperature from 3 degrees Celsius to 6 degrees Celsius does not double temperature?
Doubling temperature means increasing it by a factor of 2. In this case, going from 3 to 6 degrees Celsius represents an increase of 3 degrees, not a doubling of the initial temperature. To double the initial temperature of 3 degrees Celsius, it would need to increase to 6 degrees x 2 = 12 degrees Celsius, not just 6 degrees.
What is the temperature change in 12 degrees Celsius to minus 5 degrees Celsius?
To find the temperature change from 12 degrees Celsius to -5 degrees Celsius, you would subtract the initial temperature from the final temperature. In this case, -5 minus 12 equals -17 degrees Celsius. Therefore, the temperature change is a decrease of 17 degrees Celsius.
Why can you assume the initial temperature of ice is 0 degrees Celsius?
Ice is the solid form of water, which is most commonly found at 0 degrees Celsius. When ice melts, it transitions to liquid water at 0 degrees Celsius. Therefore, it is generally safe to assume that the initial temperature of ice is 0 degrees Celsius until provided with information suggesting otherwise.
What would be the temperature of 1 glass of cold water in celsius?
"Cold" could mean anything. To me, cold might be 10 degrees Celsius, while someone else sees "cold" as 1 degree Celsius. In science, nothing is ever described as cold, because a questions that always arise are "how cold? 20 degrees Celsius? 0 degrees Celsius? -100 degrees Celsius?"
A vessel and water have a equivalent mass of 4kg and are at 15 degrees Celsius.after a hot iron object of 2kg is immersed in the water,the temperature increased to 23 degrees Celsius ,calculate the initial temperature?

If 200g ice cube with an initial temperature of -12 degrees celsius is placed in 1 kg of warm water with an initial temperature of 40 degrees celsius If you ignore any heat losses to the environment?
The ice will absorb heat from the warm water and increase in temperature until it reaches 0 degrees Celsius. The heat lost by the warm water is equal to the heat gained by the ice. Use the equation: (Q = mcΔT) where Q is heat energy, m is mass, c is specific heat capacity, and ΔT is temperature change to calculate the final temperature of the system.
Find the change in temperature or elevation from -16 degree celecius to 23 degree Celsius?
The change in temperature is +39 degrees Celsius, as the final temperature (23°C) is higher than the initial temperature (-16°C). Elevation is not relevant in this context since it remains constant.
What is the volume in the balloon at 240 degrees Celsius?
To determine the volume of the balloon at 240 degrees Celsius, you would need to know the initial volume of the balloon at a reference temperature and the pressure conditions. You could then use the ideal gas law equation (PV = nRT) to calculate the volume of the balloon at 240 degrees Celsius by adjusting the temperature and other parameters accordingly.
What would the temperature be if you mixed a cup of hot water that is 50 degrees Celsius to a cup of cold water that is 10 degrees Celsius?
The final temperature would be a weighted average of the initial temperatures, based on the quantities of each liquid. Assuming both cups contain the same amount of water (let's say 1 cup each), the final temperature would be approximately 30 degrees Celsius.
Some small aluminium rivets of total mass 170g and 100 degrees are poured into a hole in a large block of ice at 0 degrees all the ice does not melt what is the final temperature of the rivets?
The final temperature of the rivets will be the melting point of ice (0 degrees Celsius) because the heat gained by the rivets (from their initial temperature of 100 degrees Celsius) will be used to melt the ice. Once all the ice is melted, the temperature will stabilize at 0 degrees Celsius.
What is substances specific heat?
