Answer:
6960 J/kg°C
Explanation:
specific heat= mass×specific heat capacity×increase in temperature
specific heat= 0.240×1450×20= 6960 J/kg°C
hope it helps!
Answer:
B. Aluminum is a good conductor of heat
Explanation:
Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Aluminum are as follows: Color : Silvery-white with a bluish tint.
From the equation,
4 mole of lithium produces 2 mole of lithium oxide
4.37 mol of lithium produces (4.37÷4)x2 mol of lithium oxide
Answer:
The heat generated per gram of sample in calories is 0.87 g
Explanation:
Given that,
A calorimeter made from a can is used to measure the calories in a peanut.
During the experiment, the measured calories were 35% of the true/accepted value given by references
Suppose, the mass of peanut is 0.4 g and find the
We need to calculate the heat generated per gram of sample in calories
Using formula of heat generated
Put the value into the formula
Hence, The heat generated per gram of sample in calories is 0.87 g
Answer:
The breakdown of glucose in the absence of oxygen is termed as anaerobic respiration.
Explanation:
Anaerobic respiration or anaerobic oxidation occur in absence of oxygen molecule within the cytoplasm of cell that ultimately leads to the formation of lactate from pyruvate by the catalytic activity of lactate dehydrogenase enzyme.This reaction helps in the regeneration of NAD+.
During Anaerobic respiration only 2 molecules of ATP are formed by substrate level phosphorylation .
