If 1 kg of the compound toluene melts at negative 95 degrees Celsius will 500g of toluene melt at 95 degrees Celsius?
No, if 1 kg of toluene melts at -95 degrees Celsius, the 500g sample would also need to reach the same temperature for melting to occur. It is unlikely for toluene to melt at 95 degrees Celsius in this scenario.
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
A particular sample of iron requires 562 Joules to raise its temperature from 25 degreee Celsius to 50 degrees Celsius. What must be the mass of the sample of iron?
The change in temperature is 25 degrees Celsius, meaning it takes 22.48 joules per degree of change. The specific heat of iron is 0.449 J/g degree Celsius. This means that the mass of iron must be 50.07 grams
When 108g of water at a temperature of 22.5 degrees celsius is mixed with 65.1g of water at an unknown temperature the final temperature of the resulting mixture is 47.9 degrees celsius?
To find the unknown initial temperature of the second sample of water, you can use the principle of conservation of energy. The heat lost by the first sample as it cools down will be equal to the heat gained by the second sample as it warms up. The specific heat capacity of water is 4.184 J/g°C. Just plug the values into the formula: (m_1c_1(T_f-T_1) = -m_2c_2(T_f-T_2)) where (m) is mass, (c) is specific heat, (T_f) is final temperature, and (T) is initial temperature.
If a sample is heated and rises in temperature by 12 degree celsius what is this temperature difference in kelvin?
The temperature difference in Kelvin is the same as in Celsius. So, if the sample rises by 12 degrees Celsius, it also rises by 12 Kelvin.
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
The temperature must decrease by 275 degrees Celsius to reach the freezing point of helium at -272 degrees Celsius.
If 1 kg of the compound toluene melts at negative 95 degrees Celsius will 500g of toluene melt at 95 degrees Celsius?
No, if 1 kg of toluene melts at -95 degrees Celsius, the 500g sample would also need to reach the same temperature for melting to occur. It is unlikely for toluene to melt at 95 degrees Celsius in this scenario.
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
When the temperature of a sample of water is -5 celiculs the is a?
When the temperature of a sample of water is -5 degrees Celsius, the water is in a solid state, as it is below the freezing point of water at 0 degrees Celsius. At this temperature, water molecules have slowed down and formed a crystalline structure, resulting in the solid state known as ice.
How warm should pee be for a urine sample to be considered valid?
The temperature of a urine sample should be around 98.6 degrees Fahrenheit (37 degrees Celsius) to be considered valid.
The temperature of a sample of a substance changes from 10 degree celsius to 20 degree celsius by how many kelvins does the temperature change?
changes 10 degrees C and 283 degrees K if im not mistaken which im bound to be not sure of the esential #
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
How much ice water will it take to cool the sample to 20 degrees celsius?
To calculate the amount of ice water needed to cool the sample to 20 degrees Celsius, you would need the initial temperature of the sample, the mass of the sample, and the specific heat capacities of water and ice. With this information, you could use the equation q = m * c * ΔT to determine the quantity of ice water needed to cool the sample.
If a 1.0-g sample of steam at 100 degrees Celsius loses 560 calories of heat what would the resulting temperature of the steam sample be?
80
A sample of water under study was found to boil at 102 degrees celsius at normal temperature and pressure is the water pure?
No, pure water boils at 100 degrees Celsius at normal temperature and pressure. The fact that the water boiled at 102 degrees Celsius indicates that it may not be pure and could contain impurities or dissolved substances.
Why does salt water melt faster than water?
Adding salt to water lowers the temperature at which water freezes from 0 degrees Celsius to several degrees colder than that (depending on how much salt is added). Practically what that means is that a sample of pure water at -1 degrees Celsius will be frozen solid, but a sample of salt water at the same temperature will remain liquid since its freezing point is lower that.
