Why does water get a lower density when frozen?
density is mass/volume that is the total mass per 1cm3 of the liquid in question. as water becomes colder, its particles loose energy and move closer together, increasing the number of particles per 1cm3 and therefore increasing the amount of mass in that 1cm3
What is the total number of calories of heat needed to raise to raise the temperature of the liquid water from 20 degrees Celsius to 30 degrees Celsius?
To calculate the total number of calories of heat needed, you can use the formula: Q = m * c * ΔT, where Q is the heat energy in calories, m is the mass of the water, c is the specific heat capacity of water (1 calorie/gram °C), and ΔT is the change in temperature. Assuming you have 100 grams of water, the calculation would be: Q = 100g * 1 cal/g°C * 10°C = 1000 calories.
What is total immersion thermometer?
A total immersion thermometer is a type of thermometer designed to be fully submerged in a liquid to ensure an accurate temperature reading. It typically has a long stem that allows the temperature-sensitive part of the thermometer to be fully immersed in the liquid being measured. Total immersion thermometers are commonly used in laboratory settings and for measuring the temperature of fluids.
How does volume change during evaporation?
During evaporation, molecules escape the liquid surface into the air as gas. This conversion from liquid to gas reduces the volume of the liquid as it evaporates. However, the total volume of the system remains constant since the gas molecules occupy the space above the liquid.
What is the temperatures when liquids freeze?
The temperature varies from one liquid to another. Every element has a different freezing point and boiling point. You can calculate both for a molecule by using a formula that takes into consideration the different elements that make up the molecule in comparision to percentage that element is of the total mass of the molecule
When 1 gram of water at 0 degrees Celsius freezes to form ice how many total joules of heat are lost by the water?
The heat lost by 1 gram of water at 0 degrees Celsius as it freezes to form ice is approximately 333.55 joules. This is the heat of fusion of water, which is the energy required to change the state of water from a liquid to a solid at its melting point.
When 1 gram of liquid water at 0 degrees celsius freezes to form ice how many total joules of heat are lost by the water?
a change from liquid to solid or solid to liquid will require the use of the formula of Heat of Fusion , q=mHf where m is the mass and Hf = 334J/g, this is standard so you wont have to look for how it came about.In this case the m=5.00g so: q = m Hf q=(5.00g)(334 J/g) , you notice the grams will cancel out. q = 1670 J.
How is stoichemetry used to calculate energy released when a mass of liquid freezes?
Stoichiometry is used to calculate the energy released when a mass of liquid freezes by applying the concept of heat transfer during phase changes. The heat released can be determined using the formula ( Q = m \cdot \Delta H_f ), where ( Q ) is the heat energy, ( m ) is the mass of the liquid, and ( \Delta H_f ) is the enthalpy of fusion (the amount of energy released when the substance freezes). By knowing the mass of the liquid and its enthalpy of fusion, one can calculate the total energy released during the freezing process.
How is the triangle h fusion used to calculate the energy released when a mass of liquid freezes?
The triangle h fusion, often represented as ΔH_fus, refers to the enthalpy change associated with the phase transition from liquid to solid at a substance's melting/freezing point. When calculating the energy released when a mass of liquid freezes, you multiply the mass of the liquid by the specific enthalpy of fusion (ΔH_fus). This product gives the total energy released during the freezing process, as the liquid loses energy to transition into a solid state.
How is stoichiometry used to calculate energy released when a mass liquid freezes?
Stoichiometry can be used to determine the amount of heat energy released during the freezing of a liquid by relating the quantity of the substance that freezes to the heat of fusion of the substance. This involves multiplying the mass of the liquid that freezes by the heat of fusion value to calculate the total energy released. This calculation helps in understanding the energy changes that occur during phase transitions like freezing.
How many souls does it take to level to 200 in demon souls?
It will take a total of 18,136,013 souls to level from Soul level 1 to Soul level 200.
How many nodes are there in the interconnected world of Dark Souls?
In the interconnected world of Dark Souls, there are a total of 41 nodes.
What amount of energy is released when you freeze then cool a 75g of liquid water to -20 degrees Celsius?
To freeze liquid water at 0 degrees Celsius, you need to remove 334 J/g of energy. To cool it from 0 degrees Celsius to -20 degrees Celsius, you need to remove an additional 80 J/g. Therefore, for 75g of water, the total energy released would be 75g * (334 J/g + 80 J/g) = 33,200 J.
How is stoichiometry used to calculate energy released when I mass of liquid freezes?
Stoichiometry can be used to calculate the energy released during the freezing of a liquid by calculating the moles of the liquid that freeze and then using the enthalpy of fusion of the substance (given in kJ/mol) to determine the total energy released during the process. The energy released can be found by multiplying the moles of liquid that freeze by the enthalpy of fusion value.
How is stoichiometry used to calculate energy released when a mass of liquid freezes?
Grams liquid × mol/g × Hfusion
A liquid at 20ºC is twice as hot as the liquid at 10ºC?
By the Celsius scale, yes. This is not necessarily the case when considering Fahrenheit. But the different temperature scales are relative; 20*F is twice as hot as 10*F. BUT the Celsius equivalent of 20*F is not twice as hot as the Celsius equivalent of 10*F.
