If a substance is cohesive, it tends to ______.
A. break easily
B. stick together
C. retain heat
D. hand without difficulty
সঠিক উত্তরঃ
B.
stick together
Explanation: Cohesive - দৃঢ়ভাবে একত্রে লেগে থাকে এমন। এখন, Retain heat - তাপ অব্যাহত রাখা। Bend without too much difficulty - খুব বেশি কাঠিন্য ছাড়াই বাঁকা হয়। Stick together । একত্রে লেগে থাকা । Break easily - সহজেই ভেঙে যায়। এখন, আঠাল জিনিস স্বাভাবিকভাবেই নমনীয় বা অর্ধ তরল হয়। যেমন, চুইংগ্রাম , রাবার ইত্যাদি। কাজেই এ ধরনের জিনিস বাঁকা করা (খ) ও ভেঙে যাওয়ার (ঘ) বিষয়টি বাদ দেয়া যায়। আবার, তাপ উৎপাদানকারী বস্তু ব্যতীত তাপ ধরে রাখা যায় না । তাই 'খ' কেও বাদ দেয়া যায়। যে জিনিসি Cohesive (দৃঢ়ভাবে লেগে থাকে) তা অবশ্যই together (একত্রে লেগে থাকে)।
