How does the temperature of water affect the time it takes to freeze an ice cube?
Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.
How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object. Historically the specific heat was related to SH of water . Water being 1 That now is seen as archaic. The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered. Every substance has to be measured separately .
How do you increase energy in drinking water?
The surface molecules of the water will evaporate. As the kinetic energy increases the water molecules become more free, which causes the water to evaporate.
How are the amount of heat transferred and the change in temperature of water related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.
How much heat must be transferred to liquid water to change the waters temperature from 27 degrees Celsius to 32 degrees Celsius?
To change the temperature of water from 27ºC to 32ºC will depend on the mass of water that is present. Obviously, the more water, the more heat it will take. This can be calculated as follows:q = heat = mC∆T where m is the mass of water; C is sp. heat = 4.184 J/g/deg and ∆T is 5ºC (change in temp).
What causes a more severe burn - water or steam?
Steam is more dangerous because the temperature is higher.
How does the temperature of water affect the time it takes to freeze an ice cube?
Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.
What is the difference if any of volume to mass ratio of warm and cold water?
The volume to mass ratio you speak of is usually called density, "density = mass / volume"The density of water does change a little bit depending on the temperature. According to Wikipedia, the density decreases as temperature increases, meaning that the same mass of water takes up less space at a higher temperature. Check out the details and values on Wikipedia for more information.
Does the mass of water affect temperature rise?
Yes due to something called 'specific heat capacity', this is basically that the more water there is, the hotter it can get.
How does thermal energy of an object relate to its mass?
Whatever temperature you want the mass to have, the more mass there is, the more heat energy you'll have to pump into it in order to raise it to that temperature. Or the more heat energy you'll have to pump out of it in order to cool it to that temperature.
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Water has a greater specific heat capacity.
The more mass a material has the greater its temperature?
Yes, the more mass the object has, the more temperature the object will have. Think of it like a fat person, when he sweats, he sweats more than a thin person.
Is a chemical more dangerous when dissolved by water or is it less dangerous when it cannot?
Generally water-soluble chemicals are more easily absorbed in your body and thus could be more likely to be dangerous to you
What has a greater mass 19.32 ml of water or 1.0 ml of gold?
Since gold is 19.32 grams per ml and water is 1 gram per ml they both have the same mass
What takes mass?
Nothing 'takes' mass. When adding more water to a bucket of water, the water gains more mass, but the question isn't specific enough to specify what exactly 'takes' mass.
What is the relationship between the mass of a material and the amount it can transfer?
Heat is transferred based on the temperature of a mass (relative to the cooler mass it is transferring heat to) and the heat capacity of the mass. The total heat capacity is a product of the mass and the specific heat, i.e. Heat capacity = mass x specific heat. The hotter the mass, the more heat it can transfer. The greater the mass, the more heat it can transfer per degree of temperature drop. 100 kg of boiling water could be expected to be able to transfer 100 times the amount of heat of just 1 kg of boiling water for a drop of 1 °C.
Is a pot a good conductor of heat?
I don’t know
