TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Potential energy with respect to gravity, close to Earth, per unit mass: gh, where g is the acceleration due to gravity (standardized as ≈9.8 m/s 2) and h is the height above the reference level (giving J/kg when g is in m/s 2 and h is in m).
11.6 g of NaCl is dissolved in 100 g of water. The final mass concentration ρ(NaCl) is ρ(NaCl) = 11.6 g / 11.6 g + 100 g = 0.104 g/g = 10.4 %. The volume of such a solution is 104.3mL (volume is directly observable); its density is calculated to be 1.07 (111.6g/104.3mL) The molar concentration of NaCl in the solution is therefore
Sugar is 100% carb; that's kinda the whole point. --jpgordon ∇∆∇∆ 01:05, 2 May 2006 (UTC) A restaurant packet of table sugar is typically 1 teaspoon of sucrose, equal to 4 g or 16 cal. Sucrose is 100% carbohydrate, readily digestible to about 50% glucose and 50% fructose. alteripse 05:15, 2 May 2006 (UTC)
The amount of heat required to raise one kilogram of water through one degree kelvin is 4186 joules (the specific heat capacity of water) - so we're looking at 4186 x 273 x m iceberg versus 4186 x 373 x m coffee (assuming the specific heat capacity of coffee is pretty similar to plain water). We have to add a little to the coffee's energy to ...
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
At 5 °C the solubility increases to 9.0 mL (50% more than at 25 °C) per liter for freshwater and 7.2 mL (45% more) per liter for sea water. Oxygen gas dissolved in water at sea-level
Brazil is the fifth largest country in the world, and third largest in the Americas, with a total area of 8,515,767.049 km 2 (3,287,956 sq mi), [176] including 55,455 km 2 (21,411 sq mi) of water. North to South, Brazil is also the longest country in the world, spanning 4,395 km (2,731 mi) from north to south, [ 13 ] and the only country in the ...
