Answer:
The temperature is 288, 88K
Explanation:
We use the formula PV= nRT:
T= PV/nR
T= 0,987 atm x12 L/0,50 mol x 0,082 l atm/K mol
<em>T=288,88K</em>
Answer:
Angiosperms are vascular plants. ... Unlike gymnosperms such as conifers and cycads, angiosperm's seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.
Answer:
3.2 Calories
Explanation:
Here we will use a formula
Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass
As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat is .16 calories/gm
Incorporating the values of mass (m), temperature(T) and specific heat (c) in formula.
calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C
= 3.2 calories
