How much energy is required to raise the temperature of 10.6 grams of gaseous neon from

Alona [7]

Answer:

Approximately $1.95 \times 10^{2}\; \rm J$ .

Explanation:

Look up the specific heat of gaseous neon:

$c = 1.03 \; \rm J \cdot g^{-1} \cdot K^{-1}$ .

Calculate the required temperature change:

$\Delta T = (37.9 - 20.0)\; \rm K = 17.9\; \rm K$ .

Let $m$ denote the mass of a sample of specific heat $C$ . Energy required to raise the temperature of this sample by $\Delta T$ :

$Q = c \cdot m \cdot \Delta T$ .

For the neon gas in this question:

$c = 1.03\; \rm J \cdot g^{-1}\cdot K^{-1}$ .
$m = 10.6\; \rm g$ .
$\Delta T = (37.9 - 20.0)\; \rm K = 17.9\; \rm K$ .

Calculate the energy associated with this temperature change:

$\begin{aligned}Q &= c \cdot m \cdot \Delta T \\ &= 1.03\; \rm J \cdot g^{-1}\cdot K^{-1} \times 10.6\; \rm g \times 17.9\; \rm K \\ &\approx 1.95 \times 10^{2}\; \rm J\end{aligned}$ .

Five hundred (500) milliliters of sodium chloride 0.9% is prescribed to be given over 4 hours using a volumetric pump. What's th

Angelina_Jolie [31]

Given:

Volume of 0.9% NaCl = 500 ml

Time (t) = 4 hrs

To determine:

The infusion rate of NaCl in ml/hr

Explanation:

Based on the information- 500 ml of NaCl is to be given over a time span of 4 hrs

Hence, the volume of NaCl to be administered per hr is:-

= 1 hr * 500 ml/4 hr = 125 ml

Ans: Infusion rate = 125 ml/hr

A car starts from rest gains velocity 20m/s in 10 second find its acceleration?

professor190 [17]

Answer:

acceleration(a)=2m/s²

Explanation:

initial velocity(u)=0m/s

final velocity (v)=20m/s

time taken (t)=10sec

now

v=u+at

20=0+a*10

a=2m/s²
