Question

The melting point of 1 Kg carbon dioxide is –79°C. What will be the melting point of 500gm Carbondioxide​

Answer 1

Answer:

melting point will not change it is a constant at a given pressure

Answer 2

Answer:

The melting point of 500gm Carbon dioxide is $-19750$​

Explanation:

The temperature when melting $1kg\ Co_2 =-79^o C$

Therefore,

The temperature when melting 500gm $Co_{2} = 1kg=1000gm$

$\frac{500}{2} *(-79)\\250*(-79)\\=-19750$
