How much heat in kilojoules must be removed from a glass of water that contains 100g of water to lower its temperature from?
~ 6.3 kilojoules
When 1 g of water is cooled down by 1°C it releases 1 calorie so cooling 100g of water 15 times 1°C releases 1500 calories worth of heat.
The transfer factor from calorie to joule is ~ 4.2 joules/calorie
1500 calories * 4.2 joules/calorie = 6300 joules = 6.3 kilojoules

What is the glass transition temperature of silk?
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
What temperature does glass solidify?
The temperature at which glass solidifies can vary depending on the type of glass. Generally, the solidification temperature of most types of glass ranges from about 1,000 to 1,500 degrees Fahrenheit (538 to 816 degrees Celsius).
Does ice melt faster in a room temperature glass or in a frozen glass?
Ice will melt faster in a room temperature glass compared to a frozen glass. The room temperature glass provides a warmer environment for the ice to melt quicker, while the frozen glass will keep the ice colder for longer, slowing down the melting process.
What happens to a glass of water at a temperature of 20C when it is placed into a freezer set at 10C?
The temperature of the glass become also 10 0C.
What happens when a glass of water at room temperature is placed in the refrigerator?
That would depend on three main factors: 1) The Initial Temperature of the glass of water 2) The temperature of the room 3) Time Additional Factors that could influence what happens: 1) Proximity to a heat source 2) Temperature of the surface the glass is sitting on 3) Lighting 4) Color of the glass 5) Type of glass 6) Shape of glass Heat always moves from a hotter area (higher energy) to areas that are cooler (lower energy), the outcome of the glass of water, will primarily depend on the temperature of the room and the temperature of the water. IF: The temperature of the water is lower then the temperature of the room then the glass of water will get warmer. I.e. the ice cubes in a glass of coke melting during a hot summer's day at the beach. IF: The temperature of the water is higher than that of the room temperature then the glass of water will get cooler. I.e. a glass of water freezing when set out side in the middle of winter in Antarctica. The other factors will mainly dictate how fast or slow the temperature change will occur. The temperature of the water will approach the air temperature.

How many kilojoules in a glass of skim milk?
A glass of full cream milk contains almost 10 grams of fat and roughly 738 kilojoules compared to low fat or skim milk, which has between two grams and zero grams of fat and between 495 – 375 kilojoules. Benefits of drinking low fat milk
How many kilojoules does a glass of water have?
it is a tricky subject. on the one hand, water can burn calories on the other certain types, such as sewer water can cause extreme illness which can cause weight gain. Overall though, it should have about S calories per O grams/ P milimetres/ rocket load
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What is a thin glass tube with a bulb on one end that contains liquid usually mercury or colered alchohol?
A thermometer is a thin glass tube with a bulb on one end that contains liquid, typically mercury or colored alcohol, used to measure temperature. The liquid expands or contracts with changes in temperature, causing it to rise or fall in the tube, providing a temperature reading.
How can a glass of water and a river have the same temperature but different amounts of thermal energy?
The glass of water and the river can have the same temperature because temperature measures the average kinetic energy of the particles. However, the river will have more thermal energy because it contains a larger quantity of water molecules compared to the glass. Thermal energy depends on both temperature and the amount of material present.
Why do air form vapour when you breath on a glass?
When you breathe on a glass, the warm air from your breath contains moisture. When it comes into contact with the cool surface of the glass, the temperature difference causes the moisture to condense into tiny droplets, creating fog or mist on the glass.
What happens if energy is added or removed from a glass of ice water?
If energy is added to a glass of ice water, the ice will absorb the energy and begin to melt. If energy is removed, the ice will give off heat to its surroundings and may freeze further. Ultimately, the temperature of the glass of ice water will change based on whether energy is added or removed.
What is a thin glass tube with a bulb on on end that contains liquid usually mercury?
It is a thermometer, and is used to show the temperature.
What is in a thermometer a t the bottom?
A thermometer typically contains a liquid, such as mercury or alcohol, at the bottom of the glass tube. This liquid expands and contracts as the temperature changes, allowing the thermometer to measure and display the temperature.
