A 575.4575.4 mL sample of carbon dioxide was heated to 377377 K. If the volume of the carbon dioxide sample at 377377 K is 824.7

Margaret [11]

Answer:

263 K

Explanation:

Assuming ideal behaviour and constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:

T₁V₂=T₂V₁

In this case:

T₁ = ?

V₂ = 824.7 mL

T₂ = 377 K

V₁ = 575.45 mL

We <u>input the data</u>:

T₁ * 824.7 mL = 377 K * 575.45 mL

And <u>solve for T₁</u>:

T₁ = 263 K

How much heat, in joules and in calories, must be added to a 75.0Â–g iron block with a specific heat of 0.449 j/g Â°c to increas

lianna [129]

Answer:

$Q=50,849.25J\\\\Q=12,153.3cal$

Explanation:

Hello!

In this case, given the mass, temperature change and specific heat, it is possible to compute the required heat in joules as shown below:

$Q=mC(T_2-T_1)\\\\Q=75.0g*0.449\frac{J}{g\°C}(1535\°C-25\°C)\\\\Q=50,849.25J$

Now, since 1 cal =4.184 J, this result in calories is:

$Q=50,849.25J*\frac{1cal}{4.184J}\\\\Q=12,153.3cal$

Best regards!
