What is the melting point of Lycra?
Lycra, also known as spandex or elastane, does not have a specific melting point like traditional thermoplastics. Instead, it has a softening point at around 200°C (392°F). At elevated temperatures, Lycra can lose its elasticity and degrade rather than melt, which is important to consider when washing or drying garments made from this material.
What is difference between melting point and drop melting point?
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
The temperature at which a solid melts is called?
The temperature at which a solid melts is called the melting point. At this temperature, the solid transitions into a liquid state.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
What are some really good examples of physical properties of a substance?
Examples of physical properties of a substance include color, density, melting point, boiling point, and solubility. These properties can be observed and measured without changing the chemical composition of the substance.
What are the physical properties of the element?
Whether it is crystalline or amorphous? Its boiling point, melting point, density, colour. Elasticity if it is a solid, viscosity if it is a fluid
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
Difference between arc and point elasticity?
1) Point elasticity is measured by the ratio of the lower segment of the curve below the given point to uppa segment the super part of the curve above the point. 2) Arc elasticity is measured by the use of mid point between the old & the new figures in the case of both prine and qualitiy demonded.
What is special about characteristic properties of matter?
Some characteristics are: ELASTICITY DUCTILITY MALLEABILITY CONDUCTIVITY HARDNESS BOILING POINT FREEZING POINT MELTING POINT LUSTER Some common characteristics are: MASS VOLUME DENSITY WEIGHT LENGTH
What is the difference that exists between arc elasticity of demand and point elasticity of demand?
Arch elasticity demand is the percentage change in one variable divided by the percentage change in another variable, it calculates the elasticity over a range of values, while point elasticity of demand uses differential calculus to determine the elasticity at a specific point

Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
What physical properties are size indepentent?
There are very many. Some are:Density (and specific gravity), electrical conductivity, thermal conductivity, boiling point, latent heat of vaporisation, melting point, latent heat of melting, elasticity, malleability, ductility, electronegativity (though that could be considered a chemical property), temperature.
What is difference between melting point and drop melting point?

The temperature at which a solid melts is called?
The temperature at which a solid melts is called the melting point. At this temperature, the solid transitions into a liquid state.
What is the propertie of nonmetals?
Examples: low density, hardness, melting point, boiling point, exist frequently as a gas, form covalent bonds, bad electrical and thermal conductivity, lack of elasticity, bad mechanical properties, etc.
Point elasticity of supply?
The point elasticity of supply is a measure of the rate of response of quantity demand due to a price change. The higher the elasticity, the more sensitive the sellers are to these changes.
