What is the specific heat of a metal object whose temperature increases by 3.0 degree centigrade when 17.5 g of metal was heated with 38.5 J?
Specific heat can be calculated using the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat, and ΔT is the temperature change. Rearranging the formula to solve for specific heat (c), we get c = Q / (m * ΔT). Plugging in the values, c = 38.5 J / (17.5 g * 3.0 °C) ≈ 0.73 J/g°C.
What objects float and what objects don't?
Objects that are less dense than the liquid they are placed in will float, such as wood, plastic, and cork. Objects that are denser than the liquid will sink, like rocks, metal, and glass. The shape and size of an object can also affect its ability to float.
What is the specific gravity of platinum in pounds?
Specific Gravity is unitless. To determine the specific gravity of something you take the density of the substance divided by the density of water (assuming both densities are in the same units ie: g/cm^3, or lb/in^3So for platinum, whose density is 21.45grams/cm^3 you would take (21.45g/cm^3)/(1g/cm^3(this is the density of water)), so specific gravity=21.45This would be the same answer is you had your densities in terms of lbs.
What does it mean if something is a conductor of heat?
It means that heat is transferred fairly fast through it. (A metal bar is a good conductor of heat, while wood is not). For example, you will not be able to touch a metal bar whose one end is in a blazing fire. While you can easily hold a torch of which one side is burning.
What is sprial spring?
A spiral spring is a type of mechanical spring in the form of a coil or helix, typically made of metal wire, that can store and release mechanical energy when compressed or stretched. It is commonly used in various applications such as in automotive suspension systems, watches, and toys.
What is the chemical formula for metal?
There is no chemical formula for a metal. Metals are elements, whose chemical symbols are on the periodic table of the elements.
Which metal which food is made?
iron is the metal whose food is made
What element is a soft valuable metal whose purity is measured in carats?
Gold is a soft valuable metal whose purity is measured in carats.
What determines the value of metal?
Metal value is determined by the purity of the metal. It is a commodity whose price depends on supply and demand.
A metal whose oxide is reduced only by carbon?
Aluminum is a metal whose oxide is reduced only by carbon. When aluminum oxide is reduced by carbon, it forms aluminum and carbon dioxide.
What is a useful metal whose letters are part of the word stocking?
tin
What is the formula of the hydroxide of a metal whose valency in 3?
Where M represents a generic metal the formula is M(OH)3
Is there a pacifist metal band?
Can't think of any whose specific raison d'être is pacifism or conscientious objection, but there are several bands who've written songs in protest of a war, militaristic policies, or war in general.
What is the volume of metal ball whose diameter is 25 cm?
The volume of a sphere whose diameter is 25 centimeters is 8,181 cubic centimeters
What metal ores can be mined?
All the minerals whose operation is necessary and profitable at a time.
Whose atomic number is 79?
